Very nice finish. Wish I could do the same. I got some orange peel after primed with surfacer. Now try to sand away and spray one more time.I saw some people sand up to 400 to make the primed surface really really smooth before base coat. Not sure whether that will create the wonderful finish you just showed.
Finish will shrink and crack.
What did you fill it with?
What orange color?
Caulked these last night, shot them a few hours ago.
The finish will tighten by tomorrow morning.
Sand with 240 or 320, 400 is unnecessary. You don't need to sand it away, just smooth.
Caulk is better, flexibility helps with items that can move.
You can get white hardener for auto body filler, or use Clearisil.
The Surfacer will block out the red.
