If you are painting a scale model do not waste your money on high-gloss PPG, eiter OMNI or whatever. use Testor's acrylics instead. Safe to use indoors too. Then, for the clear, use the high end PPG stuff.

Using PPG or OMNI works if you desire fore example, a super glossy Bandit or a Bobcat, where shininess is desirable. On a beaten down F-86, F-18, even a Thunderbird, Model Master works great.
Go to my gallery and check out my work using Testor's.
