As long as you can level it out to get rid of the acetone damage, you should be able to coat over the top of the existing. I think about 600 grit should do it.

Once you are down to a (relatively) clean even surface, clean off the dust and give it a wipe down with tack cloths or alcohol wipes. let it dry and then have at it again with the paint. And keep the acetone away from it!

Congratulations on passing a milestone in your building....stuffing up your first finish...it is a noble tradition and we've all been there and done it, sometimes more than once. My first build was an EXA-1 that ended up being refinished 4 times! best of luck with it!
