Caliper paint selection

When I re-vamped my calipers due to peeling clearcoat, I had a hard time finding stencils for the thicker font used on pre-GTS cars (I think GTSs had the later thinner font script). I got them from an outfit in the UK called HighgatehouseUK. They sell the decals but also the reverse to use as a stencil. I didn't get them in time for whatever event I was prepping for, so I lightly sanded the clearcoat off, making sure not to sand of the lettering, masked for the black basecoat, then lightly sanded the ridge away around the script before applying the clear coat. They turned out alright.

The Wheel Dynamics guys are pretty darn good. If you are at all on the fence about doing it yourself, or want serious show-off quality work that's beyond your own capability, go with them. They are -serious- Porsche guys.

After putting on couple of coats of clear gloss I cured those too in oven.

The write-ups I've seen from those who have stripped all the old paint off involved either aircraft paint stripper, or wire brush and sanding in more intricate spaces. If you remove paint down to aluminium then you need an etch primer before the colour coats.
The critical thing is a thorough clean beforehand to get the last dust and grease off the caliper.

Bertrand, and Stratfor, thank you, thank you, thank you, for painting the rotor hats!!!!! I see so many cars (of all types, not just the 928 world) where the owner has beautiful wheels, painted calipers, and rusty arsed rotor hats.
On my GT I went red on the rotor hats, yellow on the calipers, and red on the Porsche lettering. I used Duplicolor ceramic engine paint. Did them on the car, so they were nowhere near as nice as some of the ones presented here.

In my case the paint in the circular channel surrounding the hats is badly cracked and flaking, so I bet the paint will come out of their very soon with a few washed. I must have got my technique wrong there.
But I was determined to paint the rotors with this new set of rotors and pads. The state the rotors get into really bugs me too! I wish they came from factory with a better finish - painting them was fiddly with having to mask off the braking surfaces.

Reality includes some disassembly, particularly the SS wear plates at the ends, before blasting and finishing. not to do it. Just pull the crossover pipe, and at least one of the screws holding each wear plate inside. The heat will help with those little button-head allen capscrews for the plates.

We have a 928 we purchased a while back to try and get working on but we have not yet begun working on her.... But I'm sure we will in the next year.. And post photos here.

I'm not in the L.A. area anymore, or I'd be over there with my metric hammer and screwdriver to lend a hand with your 928. I may be down for Shartoberfest the third weekend in October, but only a short visit -- gotta get back to the Oregon mountains here before the first snowfall and all. If your project car is driveable, you should consider the Sharktoberfest even at 928 International in Anaheim.

Wheel Dynamics, If the quality of the work on your 928 mimics those calipers you presented, that will be one more beautiful 928!!! Those calipers were stunning!

I painted three sets with VHT red and they look fine, not show quality, but fine enough for me. Of course, the prep is the important part. Also, I don't think it's been mentioned but putting on the VHT or other high temp paint, you have to put on very thin coats. It's quite low viscosity and will run easily. Better to do 4 or 5 thin coats than try to glom it on and get runs. Also, I used a couple of those small stiff wire brushes in my drill to get into the convex sections of the caliper to clean it well. The paint that is on there is tough stuff, but you can get it out with a stiff wire brush in a drill and some time.

Don't forget to mask off the pistons and dust boots, and to plug the hydraulic entry thread (I used tapered rubber vacuum line plugs.
This is great opportunity to renew seals and boots which is easy and satisfying job but you really need air line to push out the Pistons to remove old seals and boots. If doing this do it after painting and oven curing. You still mask off old boots, so as not to get paint in the bores if the boots have any tear, and to keep pistons free of paint.
