[QUOTE="HND"] the fact is - A/C system is empty now and I've got an estimation from mechanic 0 (CAD) for the pipe + labour ( bumper removal etc) + 0 system refill. He didn't say anything about conversion though. So I would guess it's even more. I would like to try patching with JB Weld but Canadian Tire doesn't carry it .[/QUOTE] They certainly do. Try a different store.
