220 down to around 400/600. Then polish. You have to wet sand or dust off area or blow it off with air often to see what you are doing.
220 will take the clear completely off! If you are block sanding before buffing and polishing, start with 1500 wet then use 2000 wet. You can do it again with 3000 bit you probably won't need to. Be careful buffing, do not burn through the paint!
Wet 600 is the coarsest I would use. A better way would be to use one of the different grits of Scotch Brite. Most body shops use it now more than sand paper.
extra fine sand paper should do fine
Area will have to be sanded to get rid of the spots which will probably get into the paint. If you are careful 320 grit paper to even the surface out and reapply clear coat. keep in mind if you get into the paint it will have to be srayed color before clear is applied. Clear coat is not that bad cost wise figyre the clear, the activator about 2 Qts for what you are doing about 100.00 to 140.00 for a good clear. Where you shoot it is the problem which could be the expensive part of the deal.
theres no sanding when u do a 2 stage paint job,and ull have to wait about 2weeks tobuff the car if it was not baked under heat lamps u only bake if enamel modern paint does not require bake next question asked how long to wait after last clear coat before you color PAY ATTENTION the color coat goes on before the clear coat the clear coat is to protect and fill in any bumps in paint such as metal flake paint bottom line if you clear coat first ,you are wasting your money an your time you do not sand between color coat and clear coat sanding will take away the proper effect clear coat is to finish paint properly
do you use hardner or reducer in clear coat car paint?
Usually there is a base coat of a solid colour, a coat of the chameleon paint, and then a clear coat
I don't know about clear coat, but ferrari 's have 21 coats of paint, 14 primer and 7 paint.
If there is enough layers of clear coat let you can watersand it with 2000 grit sand paper then buff it out with rubbing compound then with some glaze made by 3m.
I always put a coat on before I paint my nails. If you leave nail polish on your nails too long, they will turn yellow. Clear coat usually protects your nails from this. Then, after you paint your nails and they dry, put another coat on to protect your nail polish from chipping and to make it look shinier!
Use a straight enamel the wet sand it with 600 grit for hour and hours and hours and repeat for coat 2 clear coat can not be painted on with brush unless you a magic paint brush lol clear over clear does not work
If there are scratches on the surface before you clear coat, the clear will not come out smooth. If you are spraying new clear coat over an old clear coat, the entire surface must be wet sanded with at least a 600 grit wet/dry paper so the surface is rough enough to accept the clear. If you are spraying new clear over an new base coat, the same techinque for prepping the surface will be necessary if the base coat has dried.
If the scratch is in the clear coat, then there is a possibility to buff it out. Deep scratches into the color coat need to be color filled matching paint color) then clear coated over.
If it is single stage paint then no if base coat then yes....
