Tamiya cans?

[sunbeam]

Hi,

Is it normal for Tamiya lexan paints to become unstuck after a few weeks?

I painted my shell 4 weeks ago and the paint on the wing started to peel last week and the body is now starting to lift where the body gets hit. You can see the paint lifting under the shell as the paint looks different?

I did strip the wing the other day with nail varninsh remover and rub it down with 1200 wet and dry and repaint, seems OK, for now.

Is it the paint, should I use fasttrax paint? Or is it my prep?

Thanks,

Rob.
