So I have the calipers off my car, cleaned, sanded and by all accounts ready to paint. I have VHT high temperature caliper paint that I will be using...then applying the stencils and finalizing with a couple coats of high temp clear coat. My question is this: Is a high temp primer necessary? My calipers are not sand blasted down to the bare metal, they have been thoroughly cleaned and roughed up using a wire brush and sand paper. Just want to make sure I get this right before starting the painting process. Thanks!

I used VHT paint and did not use primer. They are holding up well.

I have painted calipers in the past. I did not use a primer on mine. There is a thread on this do a search. Check out this website www.por15.com. They have really cool paints. I used them on my 1965 Buick Riviera I did a frame off restro on.

If the primer is not high-temp rated as well, your new paint job will likely fail once they heat up properly.

If you've thoroughly roughed up the surface, I'd vote for no primer. But make sure to wipe all surfaces down with a prep solvent before you start spraying.

Thanks guys...I appreciate the feedback and it confirms what I was kind of thinking but not wanting to do without hearing it

use brake cleaner first and apply the vht paint very thinly or it will bubble. did you remove the bleeder nipples or tape them?

Did not use primer. Just degrease and scow them up.
First coat will look crap. 3rd coat starts to look good.
Make sure they dry before you spray the next layer.
Otherwise you may find the under layer bubbling up.
I didnt even use the clear coat after the colour coats.
Its been 3 years and they look just as good as the day they where painted.
Good luck. Post some pics formthe gang.
What colour you using?

I removed the bleeder screws and have placed bolts into the holes to plug them. I'll also tape over the pistons and rubber boots. I went with red because I think it will contrast nicely with black.

Kent,
I use spray paint all the time (no, I'm not a graffiti artist) and have found that waiting 10-15 minutes between coats is fine. If you're doing a clearcoat as well, continue at the same pace, or let the color coat cure for about a week.

if you want to apply a clear coat, do not heat dry.
VHT brand is great, but I was never successful in heat drying the clear coat. It always turned to glue yellow

Andreas, thanks for the advice. I was curious what the best method would be.

Geo, I will bake them after the applying all the red coats, then I will apply the decal and add the clear. I will not bake after applying the clear. It will have plenty of time to cure.

Sounds like a plan.

Pics are mandatory!

Pics will be coming! Ill start snapping a few when I start the painting process and follow it thru out...hopefully that will help others thinking about doing this as well. New rotors should be here tomorrow and Ill button it back up sometime next week!

A little off topic, are you going to use stickers for the Porsche logo, or are you going to paint on the Porsche? Where did the stencil come from?

I don't think Kent meant to say "stencil" but decal for the Porsche logo. I have a friend that owns a plating/powdercoating shop here if anyone local wants to do car parts. The beauty of powdercoat is that it cools to a hard finish and doesn't require a clearcoat.
