By accident I ended up with a few spots that look like they bubbled up/got textured by sand paper, and I need help on how to hide them/make them look less bad. Any advice?

Strip the model and start over. I use concentrated simple green but purple power works too.

That's kinda nuclear option for a minor problem. The spots where they seem bubbled up are just on two maybe 3 spots on the whole model and aren't that big.

also congrats on 1111 posts.

(pst, the is a paintingforum)

I would try with a very fine sandpaper, say 600grit and try to repaint the primer.

Yes, strip and redo b4 the problem gets any bigger, make sure you clean the mold lines while you at it.

Purple power is the way to go now as simply green changed their formula.

PS. The problem is not small, especially after painting you can see the sandy texture where you don't want them.

You could try smoothing it out with finer grit sand paper if it's not too bad. You could sand it back and hit it with another layer of primer if you want.

Otherwise strip it.

I suggest using brake fluid, its the best stripper I've used, a couple hours ready to clean and start over.

Nail polish remover with an old toothbrush works fine in my experience.

Works for me too. Acetone free nail polish remover - soak for 10 minutes and then scrub with an old toothbrush. Comes out as good as new.

If the paint hasn't had a long time to cure (like, less than a week or so) you may be able to remove a small area of it without stripping the whole model using IPA.

IPA meaning "rubbing alcohol" and not "drinking alcohol" for the uninformed.

Yeah sorry, should have mentioned that, I use 99% IPA (isopropyl alcohol/isopropanol) that you can probably pick up in a hardware store.

I mean, I'd genuinely need to see how big of an area we're talking about to make a good decision. If it's decent enough, strip the model. If we're talking extremely small on a large model, something that'd be hard to strip all at once, I use micro sand papers. Start at something like 600 or 1200 to get the majority of it, then work in finer scales until you're down to about 12000 grit. Followed by a very thin coat of brushed on primer. But again, might genuinely be easier to strip it, as getting a smooth finish after sanding can be iffy.
