First of all, want to say thinks for everyones help in the past...

Picked up a used Borla exhaust with some slight rust on the hangers. Was gonna wire-brush off the rust and then paint it to ward off any future rust. Just around that area and maybe on the rest of the mufflers. I already have some Duplicolor Engine Enamel that says it will withstand intermittent temps up to 500 degrees. Will this be ok or do the mufflers get even hotter than that? I wouldn't think they do, but mufflers is not one of the things it lists as the paint being good for.

Other question, anyone else have a problem with the inside of their rear window getting really dirty? I'll clean it and a week later there will be a layer of something on it.

 

500 degree paint is sufficient for mufflers. Make sure to sand and prime or it'll flake off easily (yes, I have experience with that).

As for the dirt on the rear window, you may have a bad seal around the hatch or tail lights that is allowing carbon from your exhaust to get in. No easy way to diagnose this... if you have a friend with a fog machine, fill the car with fog while it's in a garage and look to see where it leaks out from. I'd say you could also try a smoke bomb, but those smell far worse than fog.

 

also the wind shield whipper the rubber piece come undo which allows water to come in when it rains try to seal it up that can allow water to move in your back hack when its open

 

Thanks good to know i can use the paint i already have. Guess i need to go pick up some high heat primer though.

No access to a fog machine. I do have aruba daves windshield wiper delete which i installed a while back with some silicon sealant. But i suppose a leak may have formed there recently. No visible wet spots or anything though.

 

Bucket of dry ice with water poured on it.....

 

This is a good idea (much better idea than recommending someone relocate a sensor that was designed to be in a specific spot lol).
