Y' know that magic coating Wren used? - Page 2 - GM Forum - Buick, Cadillac, Chev, Olds, GMC & Pontiac chat


Performance, Brainstorming & Tuning Talk about modifications, or anything else associated with performance enhancements. Have a new idea for performance/reliability? Post it here. No idea is stupid! (please use Detailing and Appearance for cosmetic ideas)

Here'* a little history behind it:

But apparently I just copied a buncha guys who painted their valvecovers, then made all that up to cover my ***.

So Bill, is this in fact the Krylon Wrinkle black?

The primary difference between these topics and a buncha guys who have apparently used it on valve covers (which I've searched for and can't find) is that I took the time to actually:

1. Investigate it further when I found it had been used for electronics cooling in tube amplifiers years ago.

2. Test it analytically on a part that actually means something to us.

3. Test it long-term to prove that my kitchen testing was valid and it would hold up to abuse.

4. Develop a known recipe that works, and is repeatable for the desired finish to be reproduced by everyone for the desired cooling effect.

(Yes, I get a little bent when someone makes light of something I've put a lot of work into, but in fairness, he probably didn't know the history behind it all).

And for the record, no. It'* not hard to clean at all. Haro also ran this on his TB during the time I ran it on the SC.

Something else people should look at.

Where I work, we have nice, high-powered halogen worklights. Same type I have at my house actually. One key difference though...the ones I got at my local auto parts store are finished in red enamel, and didn't cost alot. The ones here at work cost about double what I paid....but are finished in wrinkle coat. And I imagine they run cooler than what I have in my garage.

The old Chrysler 426 Hemi also used wrinkle coat valve covers. Imagine the heat THAT monstrosity creates.

Google search "applications for wrinkle paint". It'* more than just for looks.

Whoa, calm down. I am not saying it doesn't work. My hobby is Mustang restoration and many of the old aluminum FE valve covers were the exact same coating, that is all. Many aftermarket valve covers have the same coating. I am glad it is working for everyone. As for the cleaning I still say it is more difficult. Many parts of my 4-wheeler were wrinkle finished and they were far more difficult to clean than a smooth surface.

EDIT: Here is a pic of some Mustang valve covers. Proabably 50% of the valve covers on the market are finished in wrinkle. A lesser number of stock were also wrinkle finished. I stripped the wrinkle off of mine just because it is so common.

B2, Wren and I used the Krylon wrinkle finish. Wrens tested his pretty extensively and seems to hold well, but I did find other coatings are available. VHT seems to make a good coating that is not only heat resistant, but also comes in several colors. Have you had any experience using that, or any coating other than the Krylon? And if so, what would you recommend?

Nobody here is getting excited. I know I'm not. I do like the look the krinkle finish gives, and the heat dissipation is a definate plus for us forced induced types. But if you have any info in regards to these coatings, that would better help us figure out which coatings would be best suited for the application.

Krylon is extremely heat resistant. AT least by my testing so far (over a year). Full boost heats that SC up pretty quick in temps of 100F+.
