Is it good to use Krylob Clearcoat over Tamiya Lacquer?

[dietgilroy]

I just got primer and paint from HobbyTown, but accidentally forgot the clearcoat. Since I got Krylon clearcoat instead, will the lacquer be fine of acrylic over it?

Test it on some scrap pieces first.

Good advice there. I have some Rustoleum Painter's Touch I want to use on the interior of a B-24 bomber. I sprayed some primer on a plastic spoon, then the Rustoleum. Beautiful color and finish, but it was a bit shiny being Satin finish. I picked up some Tamiya Flat Clear today and sprayed the spoon. It came out dead flat, but the finish crackled fairly badly. It turns out I had bought the Rustoleum Matte Clear earlier and sprayed another spoon. The finish is still good, but flatter than the Satin finish and not as flat as the Tamiya. I can live with it.

Test on a cheap plastic spoon or scrap plastic! It won't always go well.

Spoons are a good way to test paint compatibility, but, you should test paint on the sprue from the kit, to be sure the paint's compatible, with that. I have successfully used Krylon clear over just about everything. It's fine over the Testors lacquers, so, it's probably safe over Tamiya's, as well, but a spoon test would be in order, to be sure!

I'm not a fan of acrylic over lacquer if that's what we are talking about here. Not even within Tamiya's own line. I've tested it. Where acrylic and lacquer meet or have been layered so to speak, down the road a piece it cracked. And it cracked deep, right down to the base substance, in this case, plastic. It looked great going on, but give it 6 months and look again.

I can also reference oil painting on this. You can have an acrylic base and oil paint over that. In fact it's common to acrylic gesso a canvas to prep it for oil painting. But not the other way around. As much as you think the oil has cured enough, then apply acrylic, it will backfire on you. Everything from wrinkling, to cracking to peeling right off. You might witness this happening tomorrow or next year, but it will happen.

Mixing brands/paint types... like starting out the evening with wine and switching to scotch. Be careful....

One clear that I've found to be safe over pretty much everything is DupliColor's 1K clear in the large can...... I know it's not what you have on hand, but something to consider trying in the future.
