im getting some rb headers, they have some surface rust, so im going to have my friend sand blast them, then i was thinking of wraping them with the fiberglass header wrap. something like this . is it going to start rusting again if i just wrap them? and will that wrap work, or are rotarys to hot? also how much of it do i need?

thanks

scot

The wrap will hold up fine if its the temps you are worried about.



The headers will rust if they get moisture on them.

Header Wrap + Moisture + Salt + High Temps= Chloride Stress Cracking

They dont use road salt in CO? New to me.





Get the header bead blasted, and do a very thin coat of high temp paint, just enough to cover it. It will be fine, I did the same with the one on my car.

To bad rotary egts are higher than that, I used a temp gun on mine after a dyno run it was still 1400 something degrees after 30 sec.
