Chemical metals, JB weld etc

[eltax91]

Hi guys

I've recently supercharged my mx5 and just got it back from the specialist who fitted the ecu and tuned it for me.

I had, for tuning, attached the charge cooler using some cable ties, as a temporary measure. I'm getting some special brackets made up to hold the charge cooler rad to the standard rad and was thinking about how to keep them still.

I was thinking of using JB weld to attach the brackets to the two rads. Question is, will it work? Is it as good as the blurb suggests and will the temperatures involved mean it won't last??

Or am I worrying over nothing and it's the best invention since sliced bread??

I've had success with Chemical Metal for repairs to pipes (fuel tank filler neck and coolant pipes in engine bay), I've not used it for anything that particularly 'loads' it so far... the repairs I've used it for have lasted years though.
I'd try it and use cable ties too for back-up...

Structurally is is quite strong and durable, but the enemy is peeling, once part of it breaks adhesion it will very quickly fall apart, bonded metal joints are often riveted , not for strength but to prevent peel. Back up the join with mechanical constraint of some kind.

Ive used chemical metal to repair cracked alloy sumps, cracked gearbox casings and porous engine blocks all with 100% success but I dont really think its meant for what your intending.
