I have a large ceiling medallion I want to copy, what is good paintable material to use? I've read suggestions to use "Lowes foam" which I assume means Kingspan Insulation foam. Is that good? Is it better than Home Depot foam?
I've also heard of "foam coat" but don't know if that's what I should use.
Also, what bits, feeds and speeds is used with foam?
Thanks!
