Exhaust rust prevention paint help

[LeeMaster]

Not sure if this should be posted here or be moved somewhere else so here goes.

I have been doing some research on google.com about coating the exhaust system to prevent it from rust. I live in one of the most dangerous exposed area for this and want to protect my system from turning old rust bucket on me.

Anyway, the question is, who in here has used something that has worked for them? This is my first time ever attempting this and want to get the most out of it. I have read that barbeque paint will do just fine because those can withstand 500 degree. I am thinking about pulling the trigger on those and be the test mule but if somebody has tried something else that worked great please share.

Heat wraps seem to be a good solution in preventing rust while also helping or increasing the exhaust's properties.

Cant water still sneak in? I never had any experience with those before but it looks like if exposed to water for a prolonged period of time water can still go through them.

Mine is already rusted....so guess ill just replace it eventually with a straight pipe...lol

Exhaust wrap traps moisture and speeds up the rusting process....unless you live in sunny socal or arizona etc....

How about some VHT? It's used on headers, should be fine on the rest of the exhaust: http://www.vhtpaint.com/products/flameproof/

Rusteloem sprat paint is really good on metal for rust prevention . but I doubt it can withstand the heat

powder coat or passivate ( rust blue or cold blue) it.

thats the only way to protect your SS from enviromental damages.

Yes, there is a problem if it's drenched in water then it may soak through the heat wrap. It takes a bit of time though, and quite a bit of water. This is opposed to the water just splashing straight onto the uncovered pipe without the heat wrap. Also, it's wrapped around the exhaust so the wrap itself will get quite hot under normal car use and you have to be pretty much driving into puddles for the wrap to get soaked fast enough that the heat generated from the exhaust isn't drying the surface. It also depends on the quality of the heat wrap, some of the newer ones are really resilient to water, but at an extra cost.

That's my take on it. I've never used it myself, but some friends have wrapped down pipes and Y pipes and taken them off a few years after with the exhaust looking pristine compared to those who haven't wrapped.

Here's the bottom of mine post-Michigan winter. I hate winter, salt, snow/slush, rust, etc. all of it. Not sure why I'm still in MI. (Summer's are great, it lulls me into a false sense of "MI is ok." then BAM! Winter.)

Holy crappers! All that surficial rust! I'd go with the VHT! Worked pretty well on my evo's calipers and engine bay. =)

EEK! I guess I will have to reconsider driving my car next winter, glad I garaged it this winter. I was checking out my exhaust pipe that has been sitting in my garage today and am very happy no rust at all.

I live in Toronto and we get A LOT of snow and salt in the winter. I can tell you none of the rust protection coating or paint will stay on. The best protection is to rinse the underneath of your car every week in the winter. We have a 10 year old Toyota Corolla, never rust proofed, and no rust, because we rinse it with clear water everyweek.
