400 Scratches in primer see through base!!!Help

Im working on a fiberglass bedcover for a dodge p/u which is the most monstorous one piece of anything ive ever seen. I wetsanded my 2k primer the last time with 400. After two coats of base (which were thin coats) i can still see the scratches when the light hits them just right. What do I need to do to fix it? Will it wet sand out or will the clear fill them?? I plan on putting two more coats of base then about 3 coats of clear. Any advice would be greatly appreciated.

If it's a solid nonmetalic color the scratches mostlikely won't show up once the clear is on. If it's a metalic just wetsand it with 600 and shoot more base on-metalic colors highlight surface irregularities (scratches, chips, dings, orange peel,etc...)

I believe, since the scratches are showing through the base, all you
can do is sand or flatten the base, re-shoot then apply the clear.

The clear will not provide much in the way of hiding, it will just amplify
what is already there !

it is metalic unfortunately. this is my first experience with any metalic paints and its not going very well. do you think just wet sanding with 600 now and applying 3-4 coats of base will be enough. there not very big just noticable when light hits it funny. one more thing what do you suggest sanding primer the last time before base. 400??600??..... thanks a lot

Since it's a metallic, resanding with 600-800 grit is probably the safest option, though without actually seeing the panel it's just a guess. Of course the base would have to be reapplied after sanding.

I agree with most of the guys.My rule is solid colors get 400,metalicsget 600.All you can do is resand with 600,and spray the base.

Can you put another couple coats on with more gun distance and see if they'll cover first?

What brand of base are you using BTW?

I was thinking of suggesting that milo, but telling someone to pile on more base might cause more harm than good. I know I have gotten away with doing that, but would hesitate to recommend it, especially to anyone who is not highly skilled, confident, and aware of the problems associated with solvent trapping.

you might want to check the tech sheets for that paint. Some recommend sanding with 600/800 before base, others I have seen say 400. If the color is not hiding very good, it is likely that they recommend 600 or 800 for final sanding anyway. If you sand it smooth, and don't cut thru to the primer, I wouldn't think that you should need that many more coats, as you are spraying over that color already.

400 grit scratches

Alittle Velvaseal hides the scratches and lays out nicely. But you will still need to sand the panel again.

Wow, Velvaseal... brings back oooold memories. Is that stuff still in use? I think it is a lacquer based sealer!

400 scratches

Yeah,velvaseal is still availabe. Good thing, too. The only fits I've had with it is when applied over un-catylized enamels. And then it's only a problem if you dont feather the area fine enough. Epoxy sealers are just too rough-looking. Use 'em daily at work for warranty purposes, but at home where my name is on the line, acrylic sealer is all I use. No orange peel to mess with the aluminum flake.
