hi all,

my car needs a new paint job, and i need some help

evry time i paint my shell with the spray cans, [custom colours] the paint goes rong, i always peels off, and flakes, the latest one i did got little blobs on the inside, even tho i was careful with the layers etc.

can any1 help me?

any advise on how to do a good job with cans? and how to prepare the shell before painting? [i hear some people sand the shell abit]

thanks alot
