Brake Calipers & POR-15

ZCAT3 · 10-11-2004, 09:31 AM

In case any of you ever want to do this, here are before and after pics of 930 calipers painted with POR-15. I used the regular POR-15 as a base coat and then the semi-gloss Chassis Coat as the top coat. I painted them with a brush, so the whole project will be about $10 in materials and a lot of time (for some odd reason I decided I needed to paint the back sides as well). The POR-15 guys say this is a great combo for calipers - 700 degree heat resistance and a very durable finish. I hope they are right.

Where did you get the POR15? I am trying to find a local (Fremont) place that stocks it.

Lookin goood! The Wurth equivalent product(Rust Guard) also works well for that sort of thing.

on rusty body parts only, I've used both Wurth Rust Guard and POR15.

I prefer POR15 having had a few adhesion problems with Wurth. Used the recommend cleaner/acid etcher systems in both cases.

looks great, looks like a good project when I rebuild my 930s.

Did you cover the PORSCHE and then sand off or carefully paint around?

Hey Shaun - the worst part of this project is the cleaning. 930 calipers have so many nooks and cranies (for lack of a better description) it is a real PITA to get them reasonably clean. I used lots of the degreaser and then treated them with the Phosphoric acid solution prior to painting but I never really felt like they were squeaky clean.

As for the Porsche logo, I sanded it clean prior to painting and then just painted over it. I painted that part last and then took a small piece of rag dipped in the POR-15 solvent and gently wiped the paint off the lettering while the paint was good and wet.

The cali distributor I used was at (800)827-6715. I think they were bay-area'ish because devivery was within a few days.

I've ordered 3 6-packs(only use what's opened) and a couple starter kits. Prep is definitive because it doesn't stick to paint well or any oil residue.

I like the product so far. The only things I worried about was the stickum/rust-sealing on the wheel arch edges, and once I got a batch that was kinda lumpy like it'd been sitting in a cold Indiana warehouse over winter.

Thanks for the pointers, I found a local place that carried it, and picked up a quart.

I hope it adheres to paint o.k. as there is really no way for me to strip the 930 calipers.

I also found it also disolved a bit with brake cleaner, which they claim it doesn't.
The good thing is it supposedly doesn't vent carrier solvent to leave micro air holes to oxydize rust. It seems like a plastic paint so I hopw it holds up on the calipers.
Looks good.

It is pretty interesting stuff. I have been using a plastic dish as my paint holder and when the left over stuff dried I was able to peel it out in a sheet. It was very flexible and quite strong. POR-15 claims that with the top coat it is even stronger so when I did the Chassis coat I painted the piece of base coat I had pulled out of the plastic bowl earlier. When that coat dried it was even stronger. In fact, I would think that you could hold your car together with this stuff. I patched a few harness belt holes in the floor of my 69S with fiberglass cloth and POR-15 and it also set up very solid.
