Arrow turbo hotside questions

Ive seen alot of pics of other ppls turbos and have seen a common trend. A nice pretty shiny compressor housing next to a rusted fugly hotside. IS there a reason why noone atleast paints it?

ALso would an aftermarket heat wrap be enough to not require the stock tii heat sheilds?

We are talking 1800F+. The only thing that will stay on that metal at that point is a ceramic coating.

Yes, a turbo blanket would work much better than stock heat sheilds.

My turbo rebuilder sandblasted my hotside.
Looked 10X's better. Atleast for 2 months. Then it got to the normal brown color.

Yeah paint won't hold up to those temps. Don't know how paintwill stay on something glowing red.

Ok, where would you take the exhaust side to get a ceramic coating?

Says it's good up to 1500F - not 1800+ but it might stick, at least for awhile.

I used some VHT High-Temp paint on my exhaust system to help prevent rust and so far, so good.

It's not something to be concerned about.
Most of it is typically ductile iron / bronze composite or sometimes expensive iron / nickel composite.
Rust is something you cannot avoid.
Try driving the car more often.
Heat keeps the moisture from settling on the metal...

You really shouldn't run without a heat shield of some sort anyway, so either paint the stock heat shield with high-temp paint like YoD did, buy a turbo blanket or go for ceramic coating.

I'm heat sheild exempt since the things broke on the rusted Jspec core I bought.

I bet my intake and coolant temps would be drastically lower if I had a blanket on but $150 is a big hit to my wallet for one.
