I like evercoat Rage gold

we just started using it and wow! we were using Zgrip and Klingspor filler but were getting a ton of pin holes. now with Evercoat rage and gold those pin holes are gone!

DaveBonds;1970002539]I'm using polyester primer surfacer (high build), gduidde coated and sanded on a 2' board with linear P320 adhesive backed paper, until I'm happy with how flat it is. This is followed by remasking out to cover all areas that I didn't include with polyester, for a urethane primer surfacer (high build)....

Thanks. My brain is processing.....
What's the benefit of switching from poly to urethane? Sealing property?
