1. According to a release by the United States Copyright Office names are not protected under copyright law. But you already said you wouldn't be using the name. Might I add though there is a loop hole to the name thing stated above. Unfair Competition Laws allow names of a brand, product, etc. to become protected.
2. Sounds like the repaint would be the same though. This would catch you. Under section 102 of the Copyright Act (title 17 of the U.S. Code), copyright protection extends only to “original works of authorship.†So as the paints would be their authorship they own it and that would put you in violation of copyright infringement.
DISCLAIMER: This above only applies for the United States of America and the information source is the U.S. Copyright Office.
Fun fact: In Canada the giving of protected material for no profit is LEGAL. However don't do it because you could still have a civil suit filed.(Wikipedia)
Didn't fully verify the fun fact.
