Hi, I normally use PLA, but if you print using ABS then you can use Acetone (Nail Varnish remover…But without any additives).
Acetone is a solvent to ABS (it won’t touch PLA). Just paint it on and hang it up if you can, first in one direction, then turn it before it’s set. If you can find a squirty bottle that won’t react to the acitone then after painting it, spray it.I’ve seen some hi gloss finishes achieved. But make sure it’s in a well ventilated space… There is a solvent for PLA, but I’ve heard it’s nasty stuff to use (bad for your health).
