The cost of the resin works out as less than the cost of buying a decently accurate spirit level...
Yer, obviously wasn't thinking when I posted lol Must be an old age thing. I was thinking you could end up with a quite thick bed of resin at one end lol but it would be easy enough to get it close to level with a spirit level. Not short of spirit levels or laser levels so got that covered, got enough resin so really just need the hardener.
Is it just resin & hardener that you have read about DC or are people adding a filler powder or something else to help
