Problems with my Tyrrell paint

[indydog]

If you've seen my post on my Tyrrell 003 build, you may have noticed the wing.

The model was painted with Tamiya TS-15 and I used an Hobby Lobby "house brand" Acrylic clearcoat. The cowl and wing were cleared at the same time. Same paint, same clear use on the whole model. Only the wing wrinkled. The rest of the car came out fine. Any ideas?






I had the same problem with problem with the nose on my Lotus 79, but that was an Enamel clear.

I try everything in the world to not mix types and brands of spray paint. Because you get silly problems like this that happen.

Tamiya lacquer is my first choice of paint and will use it from primer, to color, to clear.

Then it's model masters (testors) lacquer

Then if that's not possible Mr Color for air brush and only use that.

I keep my painting very simple, I dont use any odd ball brands that I'm unfamiliar with.

And if all else fails and have to use Krylon or something else,I won't clear coat.

I hate to see this, as your Tyrrell is a beauty of a build!

Could the clearcoat have gone on thicker on the wings than the body? Sometimes thick coats will cause wrinkles like that. Acrylic is generally okay to use over lacquer, but I would avoid any enamel/lacquer interactions. I agree with Calvin that your best bet is to use the same brand from start to finish if possible.

I have had this happen before. In my experience, it is not so much the brand intermixing, but I agree you should always try to stick with the same brand clear coat as your paint. I agree with Redlegs I know in past paintings I have done with clear coating it goes too thick in some areas it will start to react with the paint and wrinkle. It is lucky that it did it to a piece you can fix fairly easily and did not do it on the whole model. If you sprayed directly from the canister it is hard to control the flow in small areas. I try to do a real light spray of clear and another and another. That way the clear starts to act as a protector of the paint underneath.

Maybe the clear was sprayed on too heavy. It's the only thing that makes since.

That happens to me, especially when you have to hit the part from different angles. You get too much overlap and all of a sudden it's ah **** and start all over. Especially with TS13, I hate the stuff. Now I just use good old Testors, it's much more forgiving.

Agree that clear coat was too heavy. Paint masters recommend that the first coat be very thin so that the solvent dries quickly without affecting the paint. Then later coats layers can be heavier.

Thanks for the replies guys. I'll try it with a lighter hand next time.
