Found my wife's Matrix exhaust badly rusted. Tried VHT paint but work only for a few months and the paint flakes....thinking to galvanise it using galvanising paint. Search from google for more details but found that there are different comment.. Some says cold galvanise doesnt work for exhaust because the zinc will melt beyond 700+ FH..... but the others says that it works very well and easily last for a few yrs...
Wanted to check with expert in the forum on their comment before doing anything cause its a very tedious process for DIY preparation work scrub & sand off the existing paint and rust process)for spray paint....
