Do you find that some paints seem to never quite dry. I am working on a scratch build figure of mixmaster. I have painted part of the cab black since last week Tuesday. Its been a week now and black paint still rubs on my fingers every time i work on it. No doubt it will need a fresh coat of black paint when i am done. But this is getting annoying. PS I am not even using a special brand name paint, its just some cheap school-kids' paint ( it gets the job done ). How long do you guys leave a figure to dry ? Is it best to just avoid paint until all the customizing is done ?
