Just my two cents here, as I have now used both on copper head gaskets. Anybody have input on these?
Copper Coat
sprays on easily
you have to wait for it to FULLY CURE before assembling gasket
High Temp Honda Bond
messy, so apply with gloves, apply in a very thin layer
wait a short amount of time for it to tack up
when you torque the head down it goes everywhere (e.g. i am now going to need to remove the piston from the underside of the block to clean up the extra honda bond that came out under the head)
In either instance, i had to anneal the copper gasket with MAPP gas, then etch the gasket with fine sand paper to get a good surface for the sealant to bond to. Had to clean up the block and head surfaces as well.
my limited experience with honda bond makes me want to toss it in the garbage and only use this copper coat stuff.
Any pros/cons to either method?
