I've been painting some arches up today, I have been using acrylic. I was planning on clear coating them because i wanted a high gloss finish, however i have a paint run on one of them. I was planning on flatting it back slowly by wet sanding it with some 2500 grit wet and dry, then applying the clear. Can i do this? Can i just flat them and polish without applying clear and still get good results? After prep (primers etc) they have had 5 steady coats of topcoat.

 

Sorry for blurry photo, doesn't focus well on paint. 

 

 

Many thanks

If you want to lacquer them then you can flat the run off first with wet and dry and a block but you will need to key up the whole arch after with either wet and dry or a scotch brite pad to give the lacquer something to key to.

There is no reason why you can't polish up the colour coat if it is just a flat colour.

 

Although the lacquer will give you a tougher finish

Ok cheers guys. I'm somewhat a novice as you will be able to tell, so i think i'll stick with removing the run and polishing them without lacquering.

Make sure you flat it wet with 2000

Make sure you flat it wet with 2000

 

I've only got 2500, will that be ok?

It will be ok, it will just take longer to flat back is all.

 

Put a drop of car shampoo into a bucket of warm water and use that for flatting as it will keep friction down and help cut into the paint better.

keep the paper wet all the time and dry the part of regularly to check how far you have gone so that you can stop as soon as you have gone far enough to get a flat even finish

You'd have to flat the paint anyway to apply a clear coat. The exception is if this were a two-pack type paint that is clear coated within a limited time period (usually ~24 hours) of the color coat being sprayed. (The still curing paint chemically bonds to the clear coat.) 

 

Once the paint has hardened, clear coat won't stick to a glossy, shiny finish. So flatting everything is needed in any event, clear coat or not.
