My best advice:
Sand it all back off,down to the factory paint. Repair any problem areas like dents dings,etc. Go out and buy a good automotive grade primer that uses a catylist for curing,preferably the same brand as the paint that you will be using. Spray the whole vehicle like you would do a regular paint job. Let it dry overnight. Go back and scuff out any runs,trash, or dry spray you may have gotten in it. If you go all the way through the primer,spray over the bare areas with another light coat of primer. This will do two things: 1)It will give your paint a good surface to bond to. 2)It will seal the underlying factory paint from your new paint and will help avoid blistering of the new coat. After the you are happy with the primer coat,you are ready to start laying down the color. If the primer has just been sprayed over those bare areas that were mentioned before,be sure to allow enough "flash" time before you start spraying (usually 15-30 minutes-more specifics will be on the can,or in the data sheets). If you're using base/clear (highly recomended,BTW),lay down a light coat of base first. Don't try and "one coat" it. All you'll wind up doing is causing solvent pop,which resemble air bubbles in the surface. Let the paint flash,then lay down a second,heavier coat,but again,don't over do it. If you have enough coverage,and are happy with the color,let it flash. If you don't have enough coverage,one last coat should be plenty! Follow the manufacturer's instructions on flash times before the clear coat is applied. If you rush it here,you may as well have rattle-canned it
Same applies with the clear. One light coat,followed with a second heavier coat,and if needed,a third coat about the same as the second coat. If you want some in depth instructions on the perfect paint job,or proper paint gun setup,click on the link below. Good luck with it! :thumbup:
