@JonnyAlpha https://www.ebay.co.uk/itm/254290858180 sorry i forgot
ok i am having a bad time stripping the 3m underseal off it wont strip with stripper or thinners it wont sand it wont grind any ideas? of can i just paint jotun over it?
Sharp wood chisel will take the worst of it off then a wire brush in a grinder for the rest
That's only the hardened which comes in 1l tins
Even the wire brush makes a mess and it.ends up melting and collecting where the brush isint
See link to post where I removed the factory underseal with a wood chisel.
If it's the proper stone chip, like you describe, it should peel off.
It's not proper stone chip. It is 3m under seal great stuff once it's on not so great to remove.
have you tried warming with a heat gun ?
I was just about to say heat gun & chisel
I used a wire wheel on my grinder, It might be messy, But it works
@arther dailey beat me too it but - Is the 3m hard?
Have you tried a hot air gun and a chisel?
That's why I personally don't like the single pack 3M or Gravitex type stone-chips.
However the up side is if it's hard you could overcoat it with 87A.
The epoxies are brittle compared to factory stone chip and may crack if applier over them, also you will not get the corrosion resistance of the epoxy unless it is applied to the bare metal.
It is an excellent barrier so you will get some benefit.
If you are having a hard time removing the stone-chip it may be OK but you never know whats hiding under it and if it's gumming up a wire brush it isn't properly hard.
If you do decide to apply 87 over the existing stone-chip clean all the grime of it, sand it well, clean it again and apply.
3m do a 2 pack which is brilliant but hugely expensive.
Wurth, sika and dinatrol all do one that stays softish I think.
I've used the sika and it worked well, @RaceDiagnostics had excellent results with the dinatrol (I think)
I found the loose stuff came off where the underseal had cracked & surface metal had started to develop
Yes the 3m stuff has been on 5 years now pretty hard yes. I will try a gear gun and scraper or chisle later and report back. Good idea thanks guys.
Petrol and a scraper/chisel.
I tried thinners and a scraper it helped a little
Try petrol, it’s softened the stuff I’ve removed and then just scrapes off. Not trying to remove it with the petrol, just gets it all soft.
if you have used petrol been damn carefull with a heat gun or your removal problem wont be the problem anymore....
