Hey all.

First of all, gloss finishes have been my bane for the longest time since I have returned to modeling. I have had no luck doing them with airbrushes so I stick with rattle cans. Before I have had decent success with using Krylon as a base and I mainly use Duplicolor as a main coat. However, in putting together a "sample" model, I laid down the Duplicolor, 2 mist coats and one wet coat. The paint how has a less than awesome crackle look. What could have done this?

I guess I should go back to my tamiya primer...should I try to wet sand this down and re shoot or just call out the Easy Off and start over?

Did both the primer and paint "crackle"? If so, it may be the prep - cleanliness of the parts, etc. If not, it almost sounds like an enamel over acryllic or lacquer of enamel type of thing.

I had a similar experience when I primed a body that had a "high gloss" plastic finish. I ended up sanding the bare body before paint to give something for the paint to bite on.

In any case, it looks like a bath in the lake is in order.

I think the enamel (actually i think duplicolor is lacquer) is what crackled. I thought that I had used Krylon as an undercoat before, but now I recall that I actually do believe I used Tamiya light gray on the previous model. I guess I will give her a bath and see what happens.

I was going to ask what paints you used but it looks like you already have the answer, i agree the dissimilar paint is what gave the bad finish, i did this once my self i am shore we have all done this before.

Worked like a charm! I gave her an Easy Off bath and then coated her with Tamiya primer. Then I laid out the duplicolor and got a great finish, minus the few flaws left over from uncleaned paint. Im not too worried about them as this was a practice model, good thing it was!
