My current project, a bench top has a moderate amount of cupping across its ~20” width. This will be easily solved when it is attached to the support pieces. However, I was hoping to add a coat of shellac (Zinsser), filler (Crystalac) and an oil topcoat (Arm-R-Seal) in my shop and before putting it in its resting place, where this will be more difficult finish While it’s in my shop, it is held down flat. However, to get it into position, I will need to take off its hold downs at which point it will cup temporarily (each side of the 20” span will raise up approx 1/3”. Do you all think this will damage the coats? I think the cupping will cause a little bit of compression, but probably not that much.

Also, if someone could confirm that I can use Arm-R-Seal directly on top of Crystalac filler, I would be doubly appreciative. I know Crystalac is waterborn, but for some reason i think this is water born stains and topcoats.

Bonus points if someone could comment on if I should just replace the shellac sealer with a coat of Arm-R-Seal first?
