have any of you found the primer (in the US) that's needed for painting elapor foam? That's the foam used by Multiplex. I find shops in the UK that carry it but none in the US. Don't mind buying from the UK but I don't like the wait time or the shipping cost.
The Multiplex primer is not actually a paint primer. What Multiplex calls a primer is actually a liquid that is used clean the surface of the elapor foam. You then can use primer paint for you first coat of surface.
I have two cans of the Multiplex primer and it works quite well. It has toulene and some other goodies in it that I can not deciper from German to English. It smells a bit like paint thinner and acetone. You can use denatured alcohol to clean the surface but you really need to sort of etch/rough the surface for a good primer coat to stick. You can try using paint thinner, but do a test on a piece of extra elapor first. Wipe a thin coat on and wipe it off just as quick.
