rojo_143 Posted September 3, 2008 Report Posted September 3, 2008 I started to paint my engine cover last night and i noticed a couple imperfrections that i do not like. If I were to color sand it with like a 1200-2000 grit sandpaper the clean it off with a wax and grease remover when i sprayed the clearcoat on it would it still turn out shiney or would it have a dull finish? It has been a while since i have done this and i can't remember. Quote

It has been a while since i have done this and i can't remember. sand out the imperfections with 1000 grit, reapply more basecoat. dont clean it with wax and grease remover cuz it will mess up the basecoat. make sure your using a tack rag between coats to clean any dust that is on the cover and then go ahead and clear it.

mcmahan Posted September 6, 2008 Report Posted September 6, 2008 yea the tack rag is a big must it will get all the over spray and dddirt and other mess. then i would clear.. Quote
cadillacbob Posted September 6, 2008 Report Posted September 6, 2008 (edited) Automotive painter for 11 years... 1200-2000 sanding marks could be buffed out of cured/dried substrates with the proper rubbing compound/polish/finesse it type products... Go to the '3M' aftermarket or PPG web sites for more information, product desriptions, techniques...be careful around edges and take your time so you don't 'burn through'...better to slow down the wheel than to destroy all of your hard work... even with my experience, I almost near machine wheel at over 1500 r.p.m.... The aftermarket materials are always evolving and getting better... ALWAYS use wax/grease remover after sanding and prior to respraying, before applying your first coat of anything use wax/grease remover...using a wax'grease remover is not recommended over uncured surfaces, they tend to soften and pick up foriegn material from your 'rag'...also don't wait too long to reclear, it may not adhere/bite in and peel down the road...especially with 2k type products that have cured... Last but not least make sure you have enough clear coat over the base coat after removing your imperfections...just my .02 Edited September 6, 2008 by cadillacbob (see edit history) Quote
