<p>I want to paint my ABS parts. But I foresee a problem that will arise from 0.16mm layer - those layers will be perfectly visible, even with primer. Sanding them wouldn't be a good idea, because walls are just 0.8-1mm thick, and probably acetone bath isn't right thing too. I want to use some sort of cement or paste, and cover parts with it using some paint scraper or knife before painting. Do cements suitable for this task exist? Would they stick to ABS?</p>
