Various Questions Involving Auto Paint?

1. What would be the best type of paint to use to repaint my plastic motorycycle fairings gloss black using a gravity feed gun attached to a compressor.





2. What is the best way to clean out the paint gun when im finished with a particular paint.





3. What would I use as the top coat after the base color to get that glossy look of modern automobiles.





4. What would I use besides massive sanding to get the scracthes out of my plastic they are deep grooves but i dont want to sand to much because the fairings are pritty thin im thinking bondo or do they make primers that fill in little grooves?





Any help would be greatly appreciated im just inexperienced and I thought my motorcycle fairings would be a great project since they are already pritty messed up. Also I would enjoy to hear any tips that would help me along on this project thanksVarious Questions Involving Auto Paint?
1. use a primer/sealer that is meant for plastic. stick with the same manufactor for topcoating. If you are worried about flexing of the panel, you could use a flex agent but the newer paints should be ok, either for solids or clearcoats. Lacquar wouldn't be advised but is probably not available anyhow. Many of the paints today will work fine.


2. best way to clean is to rinse cup, then spray cleaner through gun with either the same thinner/reducer you sprayed with or better yet use lacquar thinner. Also, best to disassemble tip and such and soak/clean


3. Better materials (higher value) usually gives better results. Some manufactors are more user friendly then others. Go to paint suppiler and ask them and be honest about your experience. they should be able to help you. Dry time of paint, ease of spraying and environment will dictate what you need. If you have several locations to buy from, talk to all of them.


4. best thing is to sand but use the least abrasive sandpaper to remove scratches. You will need to feather edge the problem areas. leaving the scratch or chip may show up later after paint shrinks and also the area may have some grease or wax that didn't get removed.
