I've always used Slick Sand over epoxy after filler work but have recently seen quite a few very high-end shops post that they're using Clausen All-U-Need. Has anyone compared the two directly? The fact that it's water/solvent proof is appealing as that's a concern I've had with Slick Sand. How does it sand compared to Slick Sand? Slick Sand isn't the easiest to sand ( I always start with 80 grit) but it builds great and doesn't shrink so I've stuck with it, but I'm open to using other products if they're better.
For reference, I've been shooting epoxy, then skim coating the entire assembled body, a coat of epoxy to seal that, then 3-4 coats of Slick Sand for enough build to really be able to block the body straight. Before I switched to SPI I would shoot a couple coats of PPG sealer/surfacer before light wetsanding and paint, and I was always afraid of breaking through the sealer to Slick Sand. Same thing now except I'm using epoxy as sealer. So it would be great to have a waterproof poly primer, I just haven't heard much feedback on All-U-Need.
