I would like to know what would be beast product to use to seal/protect the epoxy in my aluminum cylinder head intake ports?The epoxy that was in the heads was old and was starting to crack so I ground the epoxy out and applied new epoxy in the intake ports on the heads, so I wold like to put some type of clear sealant over the epoxy.I would like to know if POR 15 CLEAR would be a good product to use? They also have a caliper paint as well.Any suggestions or input on what to use would be great. THANKS gary m

I do not know what was used the first time but I used JB WELD this time. I have used JB WELD before and it seems to work ok on manifolds, I have a new set of sb chevy aluminum heads and I plan to use splash zone 788 on these new heads, but on the old brodix sb chevy heads that I have I used the jb weld. thanks gary m

I haven't heard of its use in this app, but model aircraft dope is formulated to resist alcohol and nitro fuel blends...

Has anybody tried any of the epoxy fuel tank sealers on the market today?

Whatever the product is, not only does it have to withstand attack from fuel, it has to be resistant to high heat.

The heat/temp is a question that I have on whatever type sealant/coating to use.I think caliper paint ( POR ) has a epoxy aluminum caliper paint that I am thinking might work but I guess the only thing to do is call POR 15 as they have a toll free tech line.What would be an approiate temp range? And while I ask the temp range question what is the temp range for SPLASH ZONE 788A/788B ??? Thanks for all the repplys hope to get more info on this.
