VHT clear coat?
Has anyone painted an intake or anything with VHT Clear Coat? Just curious if it yellows like all other clears. It is suppose to be good to 1200 degrees so I would think it would not yellow but since I am considering this on a brand new intake I don't want to chance it.

I have same question regarding exhaust manifolds. Getting tired of removing and bead blasting to keep them looking rustfree. Coatings I have tried don't work.
Would like to know if the VHT Clear is an option.

Don't know if this will be comparable to the high heat stuff but I used VHT clearcoat on a spare set of aluminum wheels and they yellowed in 3 months. Never even put them on a Vette. Pain in the butt stripping them again

Looks like we're batting 0-2 already here 
I was also looking for some type of clear to use on various under-hood components to keep them "new" looking. Any other recommendations if VHT can't get it done?

I can't help but wonder how these companies that restore cars for shows keep all the components looking new without being affected by surface rust due to moisture and condensation.
How does the Pebble Beach crowd keep everything looking so fresh and new. My car is not a trailer queen, I want to drive it yet still have it look presentable but I can't devote my entire life to cleaning and polishing and glass bead blasting.

I've tried Plasticoat, Krylon, and VHT high temp clear on aluminum intakes in the past. ALL yellowed after (approx) 2000 miles of driving. Especially by the heat crossover and mount flanges. Never again. Eastwood sells a system called Zoop Seal that's not supposed to yellow. But for $89, I'd rather leave the parts natural.

I emailed Caswell who make VHT. THis is the reply I got. I asked if it would yellow on an intake and did they guarantee it won't. Here it is:
You need to order the VHT High Temp Clear coat, which has a 'flat' look to it. It won't yellow.

I've used it on cast aluminum intake manifolds, heads, water pumps, and valve covers and it lasted great and did not yellow. I haven't tried it on any real high temp applications like exhaust manifolds or on polished parts.

FYI
Here's what mine looked like after 15 years with vht clear on the intake. I used a satin finish, not glossy. The best reason for painting the intake is that dirt and grime is easily wiped off. There was some discoloring around the edges, but that was caused by gasoline leaks from the carb which formed that "varnish".

interested in opinions of others who've used high temp clear...

Clear coat Aluminium intake manifolds
I have been rebuilding engines for about 30 years and VHT engine paint is my 1st choice for long lasting results but I have always used Eastwoods Diamond Clear for bare metal surfaces and never had any issues or yellowing, it comes in satin or gloss, I like the satin on a new intake, it looks like it has nothing on it and keeps it looking like it just came out of the box, on a used intake that has to be cleaned up with a wire wheel and or sand blasting the gloss brings it back to life, the can reads safe up to 300° or 350° but I never had an issue. Just make sure you get the one for bare metal surfaces because they also make same product for painted surfaces.
