Epoxy Hot Coat more than 24 hours after Lam

Green Room epoxy.  I have read that I should lightly sand then blow off the board prior to the hot coat if you have to wait over 24 hours after lam.   Does anyone have any experience hotcoating say 2 or 3 days after lam without any sanding?  Seems like weave might be sufficient for bonding.  But I am no chemist.


I do it all the time with Resin Research epoxy.  Light sanding, then hotcoat, I don’t do any special wipedown or cleanup, other than a quick wipe with a clean rag.  And try not to touch with bare hands.  Never had a problem.
