Question for those that heat wrapped any exhaust parts
I am looking at heat wrapping my up pipe and down pipe. Did you guys use the high temp spray once the wrapping was complete? I am referring to either the Thermo Tec Hi heat coating or the DEI HT Silicone coating. The reason I ask is because the spray being in aerosol form I cannot get it shipped here to me through the mail since USPS will put it on a plane to get it to me hear in Korea (damn FAA regs).
For those that did not spray the wraps what was the short or long term outcome? pro's/con's?
Thanks

I heat wrapped and spray sealed/painted mine using $80 worth of DEI heat wrapping products from Kragen. You can save money by getting the kit from Amazon. Up pipe and down pipe should take you about 1 50 foot long x 2inch wide roll of heat wrap, ~12 of those metal zip-tie looking things, and 1 can of their silicone sealant/paint.
Soak the heat wrap in water for a minute or two before you start, this will make it slightly stretchy so you can pull it tight while you wrap it. Start wrapping at the side farthest from the turbo (on the DP, doesn't matter on UP) and overlap ~1/2 inch on each rotation. You want the exposed edges of the wrap to be facing toward the back of the car, if you start wrapping at the turbo side first then they will face the wrong direction and be more prone to being pulled off when you bottom out. It is easier if you have some help but I did fine alone.
When you're painting be sure to do very light coats the first 2-3 times. You shouldn't even get a solid color until the 3rd or 4th coat. Then you can lay it on nice and thick to seal it all together.
Edit: If you don't spray seal it then it will collect and hold water more readily. If it holds more water then your downpipe and wrap will rust/deteriorate quicker.
