Type of filler for TB porting
its adhesion is not so great (good strength though
and easy to work). You want to be sure the walls
are wetting properly, might use a bit of the resin
side to scrub with until it shows great enthusiasm
for sticking.
I used JB-weld regular epoxy after cleaning the TB
and roughing the "pockets" where the epoxy would
go, for some better "tooth". I made little foil dams
for the IAC and PCV passages and then put the
first coat on thin, just to seal, and baked it in the
kitchen oven at 200F overnight. I then did two more
build layers (J-B has no "body" to it and will slump)
with an overnight bake apiece (JB likes a 24-hour
cure but I wanted to move it along, a bit). Pulled
the IAC foil dam out afterward with tweezers before
drilling the port back open.

Damn this stuff is fun!
