69Mach1 M code 20 Report post Posted May 16, 2022 I've been using Upol Weld #2 weld through primer from a spray can for some patch panels. There are a few hard-to-reach spots where the can won't reach so I'd like to try a brush on weld through primer. It doesn't look like Upol makes a brush on primer. The reviews for SEM don't appear favorable. Does anyone have a recommendation for a brush on weld through primer that they've used and like? Quote Share this post Link to post Share on other sites
jmlay 80 Report post Posted May 16, 2022 Spray done into the cap and brush it on. or just don’t use it in those areas. Weld thru primers makes for lots of splatter as you burn through it as well as it makes porous welds. When I do use it is I scrape it or wire brush it from the direct weld area. 1 RPM reacted to this Quote Share this post Link to post Share on other sites
