Here’s a head scratcher for you. I’ve been involved in a repainting project on six HO scale passenger cars.(UP colors) I completed four with no problems using ModelMaster 2954 Dark yellow (spray can enamel) which I bought at HobbyLobby. I ran out before I could complete the last two, so I went back to HobbyLobby for more and they were out and had discontinued it. Since I was already there and nothing else is close by, I looked for a substitute and thought I found one in ModelMaster No.28104 Chrysler Yellow lacquer.(Also spray can) I got it home, followed the instructions to a T, put the first coat on and let it dry, and when I came back to it, it was crackled. It looks like when people distress furniture to make it look old, but it isn’t supposed to do that. I even called ModelMaster, and it stumped them. I live in Colorado, so humidity isn’t the problem. The next question is how do fix this without taking details like rivets off? I have since managed to find the original color at HobbyTown USA, but I can’t repaint them until I fix the crackle problem. Any tips would greatly be appreciated.[*-)]
You said that you sprayed lacquer over enamel. Or did I get that wrong?
I once sprayed Floquil clear flat lacquer over Testors silver enamel. The results were “sad”.
I have the impression that lacquer can be sprayed over enamel once the enamel has set properly. Which takes time. How much time?? Uh, I dunno.
Certainly a week, I would say. That’s how long I let Testors enamel “rest” before messin’ with it. Like spraying with Dullcoat.
If you’re NOT talking about one coat over another, but just a change in paint, then I would suspect you left a coating of “something” on the surface of the model, and that caused the paint to shrivel up.
That, also, happened to me. I always wash my models with dishsoap and water before painting. I suspect I didn’t rinse the soap film off, adequately. Either that, or the dishsoap had some additive it left on the model’s surface.
The basecoat is an enamal, but I let it set for about a week and that came out fine. Everything was clean too, as far as I know, so I have no idea what went wrong.
That confirms it to be the culprit, because I decided to take one of the cars to a local hobby shop today, and the guy there said that was likely the cause as well. Won’t be doing that again![:$] Thank you.
