Scalecoat I on Plastic

[slopes09]

Ok, so the hobby shop messed up and gave me Scalecoat I on accident, when I really wanted Scalecoat II. My question is, can you use Scalecoat I on plastic safely? I don't want to open the bottle to test it in hopes that I can possibly exchange it. If it requires primer, would Testor's gray primer work?

Thanks a lot! This is my first time working with Scalecoat.

That's my favorite brand! I use it as much as possible when painting although in this area the LHS doesn't carry it as much as I'd like.

Use it as any regular enamel paint. I have always added a little more thinner to mine, in about a 60/40 thinner to paint ratio. Adjust your airbrush to a fine spray pattern and apply thin coats. It will work well. Here's a couple of shots of scalecoat1 black on a plastic Athearn model and a caboose red resin caboose model.

Scalecote I is not recommended for plastic, but I've used it with a 100% success. I'd recommend a good primer job first, Testors should work fine.

I never heard this until I got on line, but in all my years of using SC1, I've never had a problem either.

I wonder if this got started because to get the best results from SC1, it should be baked in an oven after application.

I remember them saying something about the solvents in SCI might craze some plastics, or something to the effect. They do say that baking SCI on brass is the best way to go though!

Oh, they state on their site, that they're formulated to be use w/o primer, so with primer SCI should be fine. SCII should be used w/o primer on plastic models.

Yeah, I've had their page marked for ages. But long before there was a SCII, I didin't remember anything anywhere about not being plastic compatible. I think I still have one of the original bottles I bought when I was 15. I'll see, and try to photo/scan it.

In fact when SC first came out the only other RR. paint out there was the old Floquil. Before the EPA made everyone remove some of the bad stuff from the paints, Floquil was lacquer based, and would eat plastic alive! Now like SC, its an enamel, and quite safe.

Couldn't get the scanner to work, (think its a bad power cord), but here's a pic of that original bottle.

I opened it and it finally solidified. Well I'm diaspointed, its only 40 or so years old!
