I did this not too long ago. I have a 99 Limited and color matched the flares and side cladding. I had 1 quart and had to stretch it. There are some low spots that the milenium silver kind of shows through. Two quarts will be more than enough. If you get one gallon you will have quite a bit leftover which will go to waste. I used the brown scotch Brite pad they sell as well as their rollers. I also used bulldog adhesion promoter since the flares and cladding are ABS plastic and not metal. One piece of advice is make sure to get full even coverage on the first coat. Do not lay it on thin or else the 2nd coat will have high and low spots. You will also end up with more texture if the first coat is not heavy and even.
