yea, I just did the same. I remember having a discussion on it but I’m not sure where it is on here.
Basically it goes like this:
-For durability and insulation swaintech>all
-for moderate durability and insulation powdercoating style ceramic is good
-For good insulation without too many negative side effects go with a corrugated aluminum heat sheild:
-If you just want some temporary insulation but potentially at the cost of accelerated corrosion go with the wrap:
