Brendon_t Posted May 13, 2016 Report Share Posted May 13, 2016 Kind of finish related. I'm hoping to make a few sets of cufflinks like these using different color leads to go with different ties. The question is once formed, if using clear epoxy, can you Sand it back high enough to see through it again? Whenever I've sanded epoxy, it status cloudy.

..Kev Posted May 13, 2016 Report Share Posted May 13, 2016 Assuming you're using WS epoxy, which hardener are you using? It does make a difference in the clarity. Quote Link to comment Share on other sites More sharing options...
bob493 Posted May 13, 2016 Report Share Posted May 13, 2016 Heres the thing, "epoxy" is a grouping term ,and not all epoxies are created equal. Some are very heat sensitive, and if you use an power sander (DA, RO, doesnt matter) it will simply gum up, and theres no way back from that. Some dry really really hard, and polish up beautifully. The main difference is the cure time. If you used 30 minute cure epoxy, forget it. 8 hour stuff is probably the lowest curing time you can polish up like glass. I use 48 hour WS for "high quality" stuff. All that aside, the process is pretty darn similar to polishing a clear coat on a car. Sand up to 2000 grit, polish with a DA compound, and follow up with a polishing compound. I can recommend you some stuff if you need.

Brendon_t Posted May 14, 2016 Author Report Share Posted May 14, 2016 Yes I'm using 105/206 ws. Pictures added. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted May 14, 2016 Report Share Posted May 14, 2016 I've heard of sanding epoxy, then top coating it with CA glue for a clear finishes that polishes out well. Never tried it. Might just be a hack to try to get around the heat issue Bob mentioned. Quote Link to comment Share on other sites More sharing options...
..Kev Posted May 14, 2016 Report Share Posted May 14, 2016 I've never had clouding issues with that WS combo like you're showing except when it have finally gotten beyond its shelf life. Quote Link to comment Share on other sites More sharing options...
Just Bob Posted May 14, 2016 Report Share Posted May 14, 2016 I have buffed out epoxy with white (jewelers) compound without any clouding problems. Quote Link to comment Share on other sites More sharing options...

Try it again with 207 :-). 206 is fairly clear, but not like 207. Slow cure, no added heat and you'll be good to go. That being said, I'd sand the epoxy down to 400 then apply a clear lacquer and polish that 2 Quote Link to comment Share on other sites More sharing options...
