My car is over 40 years old and has some rust holes. I am not planning to go radical on the car and spend to much money. I would like to do most the work myself. I plan to go with a flat oxide red paint job which i would like to do myself. I am trying to find an alternative from paying somebody thousands of dollars for rust repair. I am not sure how far i plan to go with the car but i would like to do the rust repair myself.

1. what is the best way to do this with some sort of filler (bondo, fiberglass, aluminum tape, fiberglass mesh). I know getting someone to cut and weld is my best bet but i would like to know my alternatives.

2.Has anybody used the flat paint from Hot rod Flatz which is sold on Ebay by the gallon? Is it any good and easy to spray?
