Hi Again Ant, You lazy bu$$a....Epifill is just Epiglass HT9000 epoxy resin and some filler powders and some pigments....Mix ya own..much cheaper.
The epoxy repair you did wont show thru if you cover with either the Epifill or your own mix.....but....do put a layer of random mat (as I described) .. between the cloth and whatever filler you use. Will add some strength and give extra insurance against print through.
Dont get me wrong...the epoxy is the best repair in normal circumstances, however, our bodies are non-structural, therefore little load is placed on the actual body moulding.
Our preferance is for the body to stay fair and straight when it gets hot in the sun. A lot of this depends on how the body is moulded and what hard points are glassed in...ie. where the firewall/footboxes are glassed to the inside of the body.
All filling on my body has been done in epoxy...thats surface filling...not structural buildups. If I repair say the hole you made..I would use polyester to repair the hole...but would use an Epoxy filler (Epifill) for final filling after the repair cured proper.
I have a couple of mates with cobras who filled with polyester fillers (car bog essentially) and the fillers shrank over time with disasterous effects on the expensive paintwork....or it simply fell out because the amount of filler was excessive.
Tis not funny to hit a bump and have the filler fall out of ya door
