Rear Wheel Well Paint & Air Compressor ???

[rob07002]

Have a few qustions.

1) What would you reccomend doing in the rear wheel wells, POR15, Undercoating, etc.

2) Whats the best stuff to remove all the crap that in there now, Aircraft remover, etc

3) Whats the smallest compressor I can get for small paint jobs like this and small parts. No spray bombs if possible!

Thanks Guys....
