Removing paint from resin body

[asco]

Hello all!

I've located Your forum via our own Finnish model car forum. Nice rides You have here, and I've been excited with some great tips and technics. Thanks to All of You.

Now I decided to ask help from You, because I thought You must be smarter than me, and at least You must have be working with resin stuff a way more than me.

Now, to the point of this thread, I need help, pegging it, crying for it...

My beloved project got failed due a paint problem. I have absolutely no idea how to remove paint from resin body. I've understood no same kind of stuff nor ways can be used than removing paint from plastic body or parts...

So please, help noob, what to do now..?

First off welcome!

You might want to try oven cleaner for stripping. Here in the U.S we have something called Easy Off......I don't know if that's available in Finland. This is pretty potent stuff------you'll want to use gloves when putting it on. Follow the instruction carefully! In fact, just about any oven cleaner should work as long as it's the good stuff and not the "environmentally correct" (fume free) stuff.

You could also try lacquer thinner or acetone, but I don't recommend putting the entire body in the thinner.

DON'T use brake fluid to strip paint on resin bodies!! You'll end with soft mush after it's all said and done.

Some may have tried what's here in the states called Castrol Super Clean. I personally haven't used it both others may have so they might be able to give some pointers.

It looks like you tried to put lacquer paint over acrylic enamel.........bad idea! Always use the same type of paints throughout the process............it'll save you a lot of grief!

I agree almost totally with you . I take exception with the oven cleaner . I am afraid to use it on resin . Is this a workable solution ? I soak my failed finishes in Formula 409 . I aviod the dangerous fumes as a bonus . I then remove stubborn clingy parts with Lacquer thinner and a Q-tip or rag . I found this tip recently and it works well . I would be afraid to soak a resin in it though . It this possible also . I am kinda stuck in my ways .

The "purple bath" apperently works . I've been seeing that solution hailed as excellent for a few years now . As always , test on a conspiciuos area or junk part before commitring a costly prime project to possible extinction . Another cause for this lifting on your finish could be mold release . Did you soak the project in Whestly's overnight ? Then soap (without lanolin) and water wash . Thanx ..I hope this helps ..

Thanks guys.

Nail Polish Remover with rag, I heard from another forum too. Will try these as soon as I dare...

In fact, I used same type of primer from same brand, earlier was different color (gray) than the latest (white)... Damnit, never happened before, and all other parts survived, just that reson body damnit...

Thanks really a mass!

We usually use those liquids those are pointed to open drains when those have had enough hairs and butter there lol... Works like a charm on plastic parts, and won't hurt plastic at all. Brake fluid has that annoying thingy on it, plastic gets harder and is able to crack into pieces very easily.

I feel that the result for resin is the same on both liquids anyway...

Have to try that oven cleaner too... You're sure it won't harm resin at all?

Nail Polish is another thingy to try out, we'll see which one I'll locate first...

Thanks a mass anyway. First reply in other forum was "sand it, fill it, sand it..."

Yeah, I did sand it over with 600 grid paper before first wash, washed it with soap and rinsed well. Air dryed. First gray primer on it, on thin layers. Few days drying, then sand over with 600, same process, washed well with soap, rinsed, air dryed... White primer on it, and BOOM, like a field at spring..! Uh.

On Jimmy Flintstones page they claimed that there are some brake fluids those can be used for stripping paint from resin bodies, and thinner they are telling out too.

argh, I have nothing to test these fluids at all, have to be tested stright on that body... Scary, huh.

Don Holthaus from The Modelhaus recommends oven cleaner like I described above. If he recommends it, and he's the best in the business-------then it's all good.

Click here to check and see how he recommends working with resin.

I've used Easy-Off on resin before with no ill effects on it. But even next to an open door in the basement with a 20" box fan pointing outwards, it still stank! I had to vacate the basement for an hour. The paint then came off with a toothbrush.

I've also used Whestley's Bleche-White to remove paint from resin. A little slow, but it does work well.

I haven't tried Super Clean or its equivalents on resin yet.

I'd also consider re-rinsing the part before cleaning. Use a good dish soap (which removes grease,) or Bleche-White to clean it.

OK, thanks to You all. I'll check out the oven cleaner in few nights... Just have to get some spare time for it...

I'll cross my fingers and hope the best...

I got this problem solved, thanks to everyone who were disgussing and helping about on it.

I was terrified to use that oven cleaner, because of I thought it's son uncontrollable inside that foam ball it does. So I decided to try out the nail polish remover. Well with a soft rag it worked like a charm (better than mine lol)! I got the boiled areas cleaned up. Now I resanded the whole body and did wash it on soapy water once again...

It'll get new primer on it when I have the next spare moment...

Thank You all.
