Exhaust paint VHT

[stuvy]

What’s the best aerosol heat paint?

I did the exhaust on my bike a year or so back and it’s starting to show it’s age already

Any suggestions for a good aerosol please chaps

There isn’t one.

I sell a decent number of firepits and smokers. I spent a lot of time finding out the best paint.

Mipatherm is the one to get but it’s only available in a tin. Ready to spray but you’ll need a spray gun.

All the aerosols I tested, and it was most of the ones I could buy easily, were ****.

You’ll want UHT for an exhaust I’d think.

I use this guy

Pardon our interruption...

It’s all in the prep. If you can, get the exhaust off the bike and get it blasted and roughened up a bit.

I don’t think so but no pic of can that I can see so can’t be sure. None of the aerosols were very good to be honest. It’s the coverage. You need to get it on evenly then bake it as per the instructions with VHT /UHT paint. It’s quite fussy stuff. If you don’t do it right it’ll work but won’t last.

What I found anyway. I spent ages and a lot of money testing it as I didn’t want any back and touch wood I’ve had none

Weirdly enough I was at the blasters earlier and we got talking about it

I might get him to do it as he now has his vapour blaster up and running
And his burner to remove powder coat etc

Looked stunning in its plain finish

Bit of boiled linseed oil and that’ll be lovely

Dont know if any good but I got a few cans from zoro at a good price. I jmaginenthey will be acceptable for my use.

Cerakote would be a better option.

I did bake it but still looked poor to start with and if you touched it with your finger it looked awful

That stuff you need to maintain at 400 for an hour then slowly increase to max operating temp. Not sure how you’d do that on an exhaust. A cardboard box fire is about the right temp if that helps…..

I got some of this from amazon for the exhaust on my Bultaco - holding up OK so far:

Autotek AT0VHTB500 500ml VHT Paint - Black
ASIN: B004ZJIP86

The packaging was awful though - just popped in a box with no protection, one can was empty, one partially, got a refund

I warmed it with the heat gun for a bit, then fitted it up on the bike, ran the engine for a few minutes, then switched off, repeat a couple of times then off to the hills!

I did the same to mine as that’s what Iv always done

That would be a real PITA to do

Iv got a mate that’s a powder coater but they can’t get the stuff they used to use

Sadly even he can’t get anything good like the old stuff and for the life of him couldn’t remember what it was called

That’s gorgeous

Never had much luck with VHT paints, a mate used get his manifolds/pipes hard chromed, no prep apart from a sandblast and they lasted ages, looked good with all the different colours with the heat cycles

Ceramic coating is about the only thing I have seen last the test of time, there may be a diy kit available but not seen one.

Anyone tried hun blueing, would it work and be durable on a bike? @northwest

 

[OJCar]

My Guzzi LeMans 2 pipes I used to give them a clean up with Zebo Grate polish when the Sperex VHT started to look shabby

 

[Kram]

I dont think blueing is any good when exposed to UK weather. Guns etc.. will be kept/stored dry, I assume.

Wouldn't last at all, it only really works well because it holds oil and wax with it being porous. I'd be amazed if it lasted more than a day on a hot exhaust with any sort of humidity around.
