Well I can confirm that adding Methanol direct to Nitromors does nothing, Probably easier off making a batch of toffee and spreading that on hoping it takes the paint off.

Adding Dichloromethane to the new improved (OMG .. ) Nitromors stripper .
Has any one used this idea to remove aged manufacturers applied black paint ( or heat activated powder spray ?? ) on steel wheel rims /dishes that are about 5 years old or older .
As of today I have three steel rims to do , tried to do one with the modern formula nitromors and a stainless steel scrub bud ... It barely softened it for the first five small area applications on the paint over an hour period before I tried to strip it off .
Result four hours later I have one totally stripped back to bare metal rim ready for rust treating and then prepping for a colour change to wheel dish silver .
I don't relish the idea of another 8 hrs. trying to sort the remaining two rims using the new improved stuff on it's own .
3/4 of a litre of Nitromor cost me £ 21.98 this afternoon , I still have about 3/8 of a litre left & can order a litre of Dichloromethane @ £13 a litre( P&P included ) tomorrow evening if the forum thinks it should work out, at say , a 15 % addition to the Nitromor's , I'll be working outside doing it.
I might just try and stipple it on ( as is or as altered) , thick and then slip the rim into a very heavy duty rubble bag for a couple of hours to let the fumes get to work .
Most happy & exceedingly pleased to report that the 1 litre of DICHLOROMETHANE arrived to day ( eBay ) , was added at the final rate ( had a few experiments to see best rate ) 35 ml to 100 ml Nitromors and did the same with a litre of Wilkinsons similar formula paint stripper .
Armed with the correct PPE & working with back to breeze in the shade .. the dichloromethane carries a cancer warning on its label . So please do take PPE steps & to protect yourself and yours .
I stippled it on one wheel dish face at a time and then put the wheel in a steel wheel barrow with a flat 3/4 ( 19 mm ) ply cover on it for 30 min to allow the chemical reaction and to retain as many volatile fumes as I could , as these fumes also helped penetrate the paint on the wheel dishes .
Taking it off... I was able to almost wipe the softened paint off with a stainless steel scrub bud. There was very little scrubbing unlike the four hours of hard graft I had to put in on the first wheel . I used there of the stainless steel scrub pads .. when one got clogged with dead paint etc . I left it out in the sun , the stripper dried and after rubbing the scrubber in my gloved hands all the crud turned to a powder and fell out like fine grit .
Once one face was cleaned I use some of the modified cleaner on a bit of an old nappy to wipe the face clean to make sure all traces of paint were off.
All three wheel dishes are now awaiting a hot water with detergent power wash to degrease them as much as possible & for me to see if any final paint removals are needed .
Then they are in for a 3 hour bath in a warm caustic soda solution , then another warm clean water power wash & drying off in the dehumidified office in front of a small fan heater on full blast over night .
I hope to cold zinc coat , then add two top coats of silver by14.00 tomorrow and then bung them in the glasshouse with the fan heater on full blast to cure the paint a bit , ready for tyres being fitted back on , on Friday .
I got some langlow strip away pro, it is "alright" struggles with zinc primer for some reason but did quite well on a set of alloys and a set of steel wheels
Well ..... It didn't quite work out. I did one wheel rim in Hammerite rust prevention coat which turned the steel rim black , sprayed it with an aerosol of zinc primer to fill in any big pock holes then once it was two hours dry over the next five hours gave it three coats of paint . In the morning I noticed that the top coats of silver finish had puckered .. the whole thing was well & truly puckered . I scraped the paint back to find that there must have been minute traces of the original coat left in the turning groves that the steel gets when making a wheel up on a rotating machine .
I got the yellow pages to try and find a metal finisher /shot blaster / hot caustic stripper etc. every phone number I found was NU , they had died in the recession.
In the end I started touring as many paint shops /garage set up's in Swansea as I could find , 78 miles later I'm told of a new start up guy who strips paint of boat hulls etc. using soda crystals . Another 23 miles and I find his place , but he's not there , never is , he's always out doing a boat or whatever.
After a couple of hours I discover who is the landlord of the property and get the guys phone details , gave him a ring , met up with him and he did them for £15 each .. really clean job though he had to use glass beads as the soda wouldn't do the job properly . This has left the rims a bit, " sand blasted " coarse .
Yesterday and today all rims got washed in hot soapy water to remove as many glass beads as possible , the quickly dried under a 2 kw her fan heater heat in a dehumidifier conditioned room for three hours , then whilst still warm they got the rust prevention treatment , three zinc paint coats to smooth things over and after five hours of air drying the five top coats all over .. I must say it's not a bad job even from someone like me .
I hope to have the tyres and new extended valve stems fitted tomorrow .
I wish I'd found the soda blast cleaning in the place first as it would have saved me nearly £100 , for he said next time he'll do three or five wheels for a wee bit more including rust prevention, zinc base coatings and as many finish coats as it takes to do a decent looking job .
I found out that before he started his own Envo blasting business that he used to be an alloy car wheel polisher .
For anyone in South wales looking for such a guy/ service look up Envo Blast , Crofty ind est Penclawdd
really clean job though he had to use glass beads I suspect he meant glass grit, this will leave the coarse finish you mention, beads give a very smooth finish and are not good at removing coatings.
Just to add my 2p`s worth, I tried the product Tiggy-Dorset mentioned, the Boden paint and glue stripper, on my Humber project, in particular the black paint over the Ali, which Nitro-naff did not make a mark on, which under this was a brown primmer stuck down very well. So 2 applications of the Boden and im back to bare alloy. Very happy with the way it worked.
For the cost for 5ltr its good value
I bought a lot of nitromors a year or two back for a project and was amazed when i found how useless it had become, hot water had a better chance of shifting the paint. Is this down to eu or other 'elf and safety rubbish ?
Go to a proper paint merchant/supplier and buy paint stripper off them. Stuff available to the public seems to be watered/dumbed down so much it has become useless. Might as well just withdraw it from sale.
I bought 40L for a job a few months ago, god knows what it has in it but the paint fell off as soon as the lid was taken off.
The eu tossers banned the sale to the public of any strippers containing dcm/dicloromethane or whatever you want to call it june 2013. They must have run out of stupid laws concerning the correct length and curvatures of bananas that day and decided to turn their attention to stuff thats been available for donkeys years. I've never heard of anyone having a health issue with paint stripper. They'll be banning the sale of petrol because its flammable next . Vote ukip, i would if i could.
The numpties were sniffing the stripper via a bong ( modified pop bottle as the evaporator ) and getting high and even more brain damaged .
Plus , I d 10 T's were using half a gallon at a time in the house whilst the rest of the family inc babies were in it to strip doors , skirtings etc.
Yes but why not issue a leaflet stating the dangers and risks, and put one on every can sold rather than ban it ? The first port of call for the nanny state brigade ...... Ban everything that holds the slightest risk.
I think you'll find it is a euro parliament thing.. Like removing the volatile oils in gloss paint as it is said to also damage humans and the ozone layer etc.
That now means we have to have water based crud , that cracks & flakes off after four or five years ..but it is healthier to breathe the fumes ....... Apparently .
Had a pal who didn't smoke or use pubs but was a P&D since the age of 15 . The fumes from the varnishes and paints gave him emphaecemia ( sp ?) It was heart rendering to see him in his last few months struggling to breathe even on an oxygen tank supply . He died just turned 56 .
PS
You can still buy oil base gloss , usually in places like Aldi & Lidel and a few big painter / decorator centres .
I used a can of rustins strypit (think thats how its spelt) and found it very good. It has DCM free on the can but it worked as well , if a fair bit slower than the old stuff. Problem is now,i can't find anymore of it in the local hardwares.
