The high build primer mixed up much thinner and went on better, 5 coats went on, still got a bit of peel but it will block out no problem. Managed to get my hands on an FLG 5 so will use that for the base and clear.
I sanded it all down with a soft thin medium grit sponge I found in Halfords this morning, it would have been a real pain to do this any other way, I did not get rid of all the primer peel but I'm not to worried as it is only me that will notice it.
I put a bit of masking tape round the edge to keep the overspray off the top side as the inside and outside are different colours.
I got some Lechler Isolak 2k dark grey satin mixed up and used some of the high build primer hardener, seemed to work OK. All these different hardeners and thinners are a real pain.
3 coats, it went on a bit glossier than I expected.
Going well. Just be aware that hardener for primer is usually different than hardener for topcoats. May not be too much of a problem with you having a satin finish and an inside facing panel though. The topcoat hardener gives a more durable and flatter finish.
The topside of the lid is now perfectly flat, started with 180, 320, 400, 500... and finished it off with 800 grit today. The weather looks good tomorrow so will finish it off then.
The colour will be metalic blue, Merc finish off the boot lid inside with dark grey satin.
If it all works out tomorrow the next job will be the Jag front wings which are bubbling round the arches, if not all this clobber will be going back on to ebay.
After the first coat of base I was horrified to be able to see lots of fine scratches all over the lid, thankfully they disappeared after a couple more coats of base.
This is after 3 coats, but I could already see some specs of dirt in it.
Next two coats of clear, and more specs.
I will sand down with some fine grit and polish, but if I can still see the specs I will put on another coat of clear tomorrow.
Any suggestions on prep work for another coat of clear?
The norm is to panel wipe each coat and then use tack rags before spraying,did you do this?
I'd have sprayed that side on rather than sprayed it flat simply because your reach movement over it is creating dust particulars to hover and land on the panel whereas it being sprayed side on will get less chance of accumulating dust particles
Used panel wipe and a tack cloth before I started, that was it, I haven't seen any one doing any more than this but then again I've been watching videos of guys in clean spray booths. I'll try verticle next time.
It just makes sense to use a tack rag on each coat rather than be annoyed when the paint goes on and find they're there,even the cleanest of enviroments have dust particles floating about.
