Bubbles in Paint

Painstripper? Meh!

Plan C.

Currently under serious consideration.

If you want to use rattle cans, go to an auto store and get the Dupli-Color paint in the color you want. I did that on my SG junior project and it came out great. That paint is acrylic lacquer it should be fine with what you have as far as sanding sealer or filler. Their universal black is great. You’ll want 3 to 4 cans and a bowl of warm water. Spray with one can, light coats and when you feel the can get cold in your hand switch to the next can and place the one you were using in the water. If you keep using the same can, it can cause it to spit which will cause you more problems. The nozzle on those cans is also fanned and you can change the direction to be vertical or horizontal. Spray 6 to 8 inches away from the surface. Good luck.

Instead of debate, you prefer to bait. We see how you are.

OK. Yeah, right. What was it that I said that you consider "a bait"? That he shouldn't use a water-based stripper? (Have you seen a doctor about your problem.)

Look Goober, I'm not going to nit-pick with you. There are many water-based paint strippers on the market. I was merely advising NOT to use one of those.
"Any idiot knows you don't use water on a guitar". I guess I am an idiot, because I know you shouldn't use water on a guitar. I guess you also are an idiot.

Apparently, you agree with me. So, why all the arguing and name calling?!

No, what you actually wrote was, "Definitely DON"T use chemical paint stripper! That makes a horrible mess and leaves a residue that needs to be thoroughly rinsed off with water."

If you had said, "Don't use a stripper that needs to be rinsed off with water" I don't think there would be an contention with that sentiment.

Larry, I see what you're saying. You are absolutely correct.

They all leave a horrible mess that needs to be rinsed off. That's the main reason I advise against chemical strippers. If I would have added that some of them need to be rinsed with water, it would have been better.

Even so, I don't see why Goober has to get so riled up. He could have merely said that he uses CitriStrip that uses mineral spirits to rinse off not water.

Make sure you're spraying very lightly and allowing everything to dry properly between. Multiple light coats will lead to a much better finish than fewer thick coats.

This right here.

I’m still really curious about this situation.

What were the temp and humidity conditions when you sprayed/dried? Any photos of the bubbling for the more experienced members to look at?

I’m inclined to agree with sanding to scuff and smooth, duplicolor primer, black lacquer and clear, as long as temp is higher and humidity is lower.

I’m working on a Rustoleum project for my son’s pinewood derby car (more to come) and trying to keep all of these tips above in mind.

Generally 70s and around 70%.

I think the real problems are that I have absolutely zero patience and that I have to try and squeeze in painting when Her Maj doesn't notice. She gets really ticked off if i so much as think about my hobbies. Therefore, too much paint, too thick, too quickly. The skin on the paint would cure, but that prevented the solvent in the paint underneath from evaporating smoothly.

Yes, that's right. Painting/finishing requires patience. Several even, thin coats with plenty of drying/curing time in between.
Rushing it not only can result in the bubbles you experienced, but also can lead to sags and runs which are next to impossible to correct in anything other than lacquer.
