just use filler primer spray paint

I like this one, works p well at hiding layer lines.

So I'm trying some different smoothing ideas for PLA and hoped I could get some input.

Tons of sanding doesn't work alone.
Wood glue is a failure because it doesn't smooth enough and can crack off in a chunk putting you back to square one.
Bondo filler works fairly well.
Automotive filler primer also does okay.

So far the best thing has been bondo and automotive filler combo with a lot of sanding and layers as been the most effective. For sanding I've used fine grits, polish paper fine paper, and even car polish which is basically sanding paper goo.

No matter what I do so far I really can't get it to a polish. The 3D print lines are gone, but then it almost has a texture from the paint itself I can't seem to smooth out. Its fine, but its there.

Any suggestions? Wet sanding? Or some kind of polyurethane or lacquer maybe? (I've tried clear coat but that still didn't work)
