Have seen posts about folks using these over Epoxy hotcoats… but can’t seem to find the answer to this question:
what grit do you go to on your hotcoat prior to spray? was thinking 100…
thanks!

I havent tried it over epoxy yet but I do have a can and it shows prep 280-320. I have been waiting to try the UPOL on something other than clear coat on a bike repaint…
There are a few guys here that use UPOL over epoxy and they most likely will give you the straight scoop.
On another note I have had great results with water based exterior polyuretane over epoxy prepped to 220. It does seem to yellow a bit but I like the seal it forms. Im just trying to stay away from the more hazardous chemicals when I can…
