baking VHT paints

Post by **wibble_puppy** » Sat Jun 30, 2007 2:02 pm

not really "bodywork", but it's about paint so here goes (mods please move this if appropriate

)

Have any of you used VHT paint and found a place and/or method of baking it on to the parts (manifold, brake drums etc) which doesn't involve using a blowtorch?

Am trying to contact the manufacturers for advice. This stuff is pricy and I want to do it properly!

Cheers for all advice,

Hot oven!!

I've just baked some Hamerited brackets in the oven at 100 C for 30 mins.

I guess VHT will need a hotter oven!

This by the way explains the unique flovour of my cakes!

Continuing the domestic theme I've just been cleaning under the bonnet with her toothbrush!

Isnt that the stuff thats meant for exhaust manifolds?

Yes, but DIY shops sell pretty much the same stuff as "barbecue paint."

seriously for once

The manifold will get hot the first time you use it and bake on the paint.

The brakes probably don't need VHT I just use hamerite and only a thin coat at that, just for cosmetic effect.

Jonathon will probably know the best way to achieve this.

what about using a heat gun?? about £11 or so from Machine Mart. These get things very hot but not as much as a blow torch

Barbeque it?

We seldom use VHT paint I'm afraid. On drums we'd use smoothrite, sprayed on or 2K black. Engines are 2K also. If we do use VHT on the manifold then its just sprayed and the engine run upto temp to help cure it. Sorry no magic potions, well not for paintwork anyway!

thanks for your replies, guys

the problem with the hot air gun/blowtorch method is that the paint needs to be baked at a series of very specific temperatures - at least that's what it says on the cans.

*scratches head* on the cans it also says you can bake it on by running the engine (if it's a manifold) - so how come that works, if it's got to get baked at all these specific temperatures?

understand i do not

ps one brake drum is already painted....

Sweet talk the Site Manager at the local high school... they are bound to have a kiln ;)

What exactly do the instructions say? I imagine it'll be fine as long as you manage to get it higher than the temperature it cures at.

Hi alex,

the instructions say to bake the paint at a specific temperature for a specific length of time, then to bake it again at a higher specific temperature for a different length of time, then to bake at the highest temperature for a short time.

*scratches head*

I reckon the kiln is only way to bake these things to 1000F.

Do schools really have kilns these days??

I so wish mine had had one!!!

Find a specialist art college or high school, I know of at least 10 in my borough that have at least 1 each. The one high school in the centre of Dudley has 4 kilns!
