Heat Resistant Paint

A lot of high temperature paint seems to need high temperature to cure and is very fragile until then. Is there a paint, suitable for e.g. the silencer, that will cure at room temperature and not burn off or discolour at the first sign of heat?

 

I've noticed the same. I do use the temperamental VHT paint from Halfords on my silencer, and it seems to bake on nicely after a drive.

Well that's the thing. I want to get it painted, but it might be a little while yet before I get it cured. In the meantime it's bound to get scuffed, scratched and chipped before it is fitted

 

As VHT is about the most useless paint about until it cures , its just powder , will not stop rust .
Reading instructions for curing off the car, you wont get it hot enough(350C) before going for a drive, just be very careful.
.
Maybe even find some other easily strippable waterproof paint to stop rust, and leave the final painting until later...

 

Hi temp paint is fairly useless. Rustoleum Combi-Color is rated up to 80*C. Might give that a go?

 

Silicone Enamel paint is good for 500C, cold cures.
I haven't used it, but looks promising, searched it out last time as the previous high temp spray paint never cured properly.

 

Brilliant! Searching for "high temperature enamel" brings up a lot of options. Thanks!

 

Tell how it goes.
Never really seen good results on exhaust other than ceramic coating.

oh - and engine oil for the industrial look

 

i did vht on my old exhaust - didn't last. current exhaust i had ceramic coated and it looks as good as the day it was done.

heat exchangers i did in rustoleum as they get hot, but not hot enough for vht - they are looking good still.

 

I think the problem with VHT is it needs to be gradually heated up until things melt and that might need say 15 miles of 55mph plus on a motorway.
Miss that baking, it simply washes off with rain..
Ceramic coating or "stainless" that also goes black where it gets really hot and starts rotting, but slower than mild steel sprayed gently with water while really hot .

Then the stainless steel cracks ... I got about 10 years/80k miles off a stainless silencer box.

 

When I had my westy I sprayed the visible parts of the stock silencer with silver VHT at the start of every year. No prep, hold up some cardboard style. Looked good to a man on a galloping horse.
