help! stubborn mold release

[lemansnut]

Just started working on the Scale Designs Alfa Tipo 33/3. I've sanded the body and soaked it in household bleach overnight then when I went to prime it, it seemed to repel the paint. I can only guess it's the mold release still on the body. I've wiped it down with acetone to remove the primer then tried again with the same result. I cleaned it again with acetone then scrubbed it with alcohol and still get the "fisheyes". Any ideas on what I can use to clean this thing off?

Thanks,
Mike

Have you tried regular dish washing detergent in warm water and using a scrubbing brush? Usually works for me.Otherwise if this fails I use panel wipe which is available at most car paint suppliers.It's a spirit based cleaner and degreaser that pro body painters use before painting to remove all excess oils,grease and foreign residues.It's safe on all surfaces,plastics included.A large 5 litre container cost me only £5 and will last for ages.

When I ran into problems w/some resin that had a terribly greasy mold release that was stronger than pure lacquer thinner, I ended up having to strip the paint (that pulled away in sheets, I didn't even get fisheyes it was so bad) with Easy Off oven cleaner. And after that, the resin finally was stripped of the ungodly mold release that had every other "solution" tried; Westley's didn't work. Naptha didn't work. Wiping with parts cleaner didn't work. Wiping in pure lacquer thinner didn't work. Soap and water? Yeah, right!!! If lacquer thinner didn't work, soap and water weren't touching it. Damn thing was still greasy!

Now when I have resin that feels like it's got this horrid mold release (greasy) it gets a quick shot of Easy Off (full-strength stuff, not odorless), I let it sit for a few minutes, rinse it off carefully, and I've had no problems since then. Even a resin caster from Canada told me that was a good idea for resin prep, he did the same thing. Not all resin requires it, but it seems impervious to the oven cleaner.

JK. . .lol

Westley's has always done right by me. . .

One guide line that I have learn in resin is to remove any mold release first before sanding. Reason being is that you can push the mold release deeper into the resin. Use Westleys, Easy-off the strong one not the one with out fumes remember to do it outside. I've clean 1/43 bodies with a quick dip in laquer thinner.

I use Nitro solvent (Toluene) succesfull to clean or strip resin, strange you got troubles with acetone. I checked my SD Alfa 33/3 and the resin seems great, clean, dry.

Thanks, I finally got the body primed. For whatever reason, my Plastikote brown sandable primer seemed to work fine. I had tried the grey first, also Tamiya and Krylon. I'll give the Easy-Off a try on the rest of the parts.
