- Tips From Our Customer - by Ks Prei -
- Sand them out using 222 - 230 fine sand grit paper
- wipe it down with acetone or denatured alcohol
- use set of metal picks to easily clean out the residue
- squeeze a little water from rag into a hole to take our traces of dust/residue
- used the pick tool again and blew out the water.
Viola! A perfectly clean, residue-free hole!
Hope this "short" story helps someone else with those annoying air bubble holes!
