Minor scratches showing through after 1st repair attempt, proper fix?

F

Fastback

OK, so my small parts had some build up of UV clear on the edges and some trash showing, by the time I was through cutting those edges (and burning through) and removing the trash I did a recoat with the color and then re-clear. This was after the part sat for a week.

But, I must have use the wrong grit at some point and now after buff I see some really fine straight lines under the clear. Its possible they were there before my repair, I cant really say since I did not buff the part before the repair, but I did seal everything before initial color first and it looked perfect in base.

Whats the best method to repair this? My plan was to go over it now with 1500 and more base, let it flash and then re-clear? Should I let it set in the sun for a few days to harden up first or should I seal it again and start over?

Right now, after the UV clear (one day old) is hit with the 1500 nothing shows up, even when wet, but I know they will pop once the clear is buffed.

What should I do for problems like this?

Thanks,
Alex
 
Not enough info to say, but it sounds like you'll be repainting it a third time?

Is this a metallic color?

Sun for a few days could not hurt, 2 paint jobs in a row is a lot of film build and there will be some solvent in there still. By them you'll have gotten a better idea of what to do.
 
It has metallic in the name, "Caspian Blue Metallic" but its a very mild metallic, just enough.

These are smaller parts and I really dont plan on building up anymore than I have to. I did not load up the base last time, just blew some on to cover with my touch up gun.

I guess I will just wet sand it down well into the color coat and try again with more base/clear. I let it sit in the sun for a few hours today, Ill just start over later in the week. I guess I just got in a hurry since these were "Small parts", lesson learned.
 
Would you say that the scratches are visible in the metallic? I have had that happen when using too coarse of a grit painting a metallic color. Fine metallics seem to be the worst at showing off every little defect. If you need to limit the amount of basecoat used, sand with 800 and apply one coat of intercoat before moving to two coats of basecoat. Minimal applications of basecoat are fine for solids, but with metallics there must be enough film build to hide sanding scratches.
 
ugh. the silver ghost flames in my sig showed ever imperfection. surface had to be perfect. got lucky on tank and rear fender. re-did front a few times...

can you post a clear pic?
 
Like Crashtech said. We have learned that for Metallic basecoat use 600-800 and nothing courser. Solid base 400 is okay. We however ran into an issue where after a few weeks on a solid tank, teeny tiny sand scratches started to appear all over. Talked to a few people on here and said it was most likely due to not allowing proper exposure to the sun before buffing.

Also, you are asking about 1500 over clear for more base? I may get corrected here but again, I would use 600 over the clear if you plan for more base. 1500 seems too fine for good adhesion.
 
Yes, using 1500 does concern me also, but I have nothing under 600 in wet and apparently that left scratches. The only thing I can figure is I let it run dry or had a piece of trash under it etc..

I may go with 600 again on the prep for base.
