Getting paint to stick.


Recommended Posts

Would I have any luck painting the back half of my turbo and the turn down elbow on the back of the turbo to the exhaust pipe. Mine is pretty rusty. Does the temperature of these items typically exceed the ability of high temperature paint?

Well the EGT's can go up to 1400* potentially. I dont know of any type of paint that would work that hot. I know even engine block paint is usually only good up to about 550*. Plastikote does make a "HI-TEMP" paint that is supposed to be good for headers and stuff. They say it is good for up to 1300* intermittently. Not sure if that would hold up for long either. Couldnt hurt to try I suppose.

Do some checking around and find wood stove paint. Like I've got a wood stove and its painted brown and with stands a heck of alot of temperature being the pyrometer daily would be pushed to 1,400*F for at least 5-10 minutes.

 

As for engine paint most of that stuff would just burn off.

 

I would suggest sandblasting the turbine housing and get as much rust off and give it a rough finish that paint could adhere to well.

I wouldn't sandblast anything unless you're going to rebuild the turbo, blasted sand gets into everything! Ka-blewy!
