be careful when you paint your "Paint Isolator" on there mate.
To seal it up and stop it bleeding through it'll have to be a 2pak product, ie. isocyanate filled. ie. very bad for you.
Especially if you are painting it in a non ventilated environment. (ie. not a spray booth).
Not trying to be patronising or anything to you. And if you are already aware of this please dont be offended. But as a relatively young (29) spraypainter i am very passionate about personal safety as i see all too much careless practices in my industry.
I'd hate to see a fellow mini lover in being put in danger. After all, we are very special people and should be treasured above all others
On a brighter note . Please chuck up some photo's of your progress as i'm sure everyone, myself included, would be keen to see your project.
