I'm not with Rob Macks on some things, but he's right here - use a foam roller and tip off with a foam brush for the fill coats. Put them on thin and do 4 fill coats if you need to. (depends on the vicosity of the epoxy) I like to warm my epoxy if I am wotking where its under 65 F.

: I'm using the thin plastic scraper/squeegee approach I did for the
: fibreglassing but as I spread it across the bumpy surface I'm getting
: loads of foam.

: Should I use a brush or roller? Or just apply heavier? I could try but rather
: than make a mess if anyone has a strong opinion before I start the next
: round could they let me know.

: Thanks in advance,
