I have been following this for a while and I dont have a car that needs paint, I did need to paint my toolbox. black truck with a black truckbox. I d/a'd it with 220 and used black paint thinned with a little min. sp. and rolled it on, THICK the the next day I wet sanded and rolled it again, and left it. both times there were lots of little bubbles that flowed out within minutes, but overall I think this is great! I did minimal prep, and was not real careful with it, put the paint thick and only sanded ith 220 both times and I think it looks great, I am not real concerned because its a tool box and going to be beat, but I would not hesitate to do this to a car I can only imagine the results that you could get if you took more time than I did, and also dont drive while the paints wet.
