Q/A & Help Group 9 years, 6 months ago Hi everyone! I have a question about painting an inner frame of an MG. Ive painted one before using Vallejo Air paint, but I may have made a mistake of not top coating it. The problem is that the paint is chipping on the joints or every time I move it. Is it because I didnt top coat it or not enough time for the paint to set. Is there a safe way to paint an inner frame that it could still be used and be posed for photography?

I’ve not used the Vallejo air paint, so I’m not sure on how it behaves. I generally do paint inner frames though, usually Tamiya acrylics or Alclad and yes I top coat, usually with Future Finish.
Such a combination usually works well, but I’ve found that it won’t withstand heavy physical handling, especially if my hands are hot and sweating. That won’t lead to chipping paint, but it will eventually rub off.
Are you using a good primer? I like the Alclad grey primer very much and I think that does help give the paint a good stick to the model.
It maybe the primer I’m using. I just bought one off the hardware store here. I just bought a Vallejo primer the other day, but I haven’t tried it yet. Trial and error I guess. heehe
I always used to use generic car body primer before I got my airbrush and never had bother with it, but then again, I wasn’t building Gundam mechs back then! I’ve not tried the Vallejo primer so I’ll be keen to hear how you get on with it.
Thanks also for replying! 🙂
It’s best to choose the primers that say they’re specifically for plastic. You can go to your local hobby store or arts and crafts store, then find the paints section. I used generic paints that list plastic, and they’ve worked just fine. 🙂
For topcoat, be wary of the ones that advertise “2x thickness” as they cake the plastic really easily.
Thanks for the tips mate! I’ll see whether if I still want to paint the frame yet, I’m doing it for the beginner challenge plamo competition.
you may also want to keep in mind that paint does actually have a thickness to it, if you’re movement is too stiff if could be the paint rubbing and then no amount of topcoat or drying time will fix that, what you’ll need to do for that is sand the surface to give the paint that little extra space it needs
Thanks for replying mate! I will try that next time I do a frame.
I think I may have solve part of the problem, the primer I was using was meant for plastic but I guess it was just too thick to be used on hobby grade plastics. Thanks again for the help guys!
