I was pressed for time so I did not properly prep or paint my calipers. Yet the results were outstanding! I had to place the car on a stand one wheel at a time and work on it late at night. That by itself rendered the epoxy systems unusable for my situation.
List of materials/tools:
1. Brake cleaner
2. Wire brushes (small and large)
3. Masking tape
4. Small knife
5. Tweezers
6. ½ inch brush
7. Foam brush (didn't like the way it worked)

I used a wire brush to remove the light rust off the calipers and then used brake cleaner to wash off the rust and brake dust. I have NOT used "degreasers", metal preps, rust reformers or anything else. Through trial and error, in my case, I found out that the paint worked best when brushed "thick". Brushed on just short of "dripping", it self-leveled and covered amazingly. Brush marks disappeared almost immediately. The paint stuck to the metal perfectly and was very easy to spread accurately so it does not cover pins, rubber seals and moving parts.
On the first caliper I tried to use the foam brush as per other reviews. It did not work well in my case. I did two coats of paint after cheating and using a heat gun on the first coat to shorten the dry time. The second coat looked "OK" but not as good as the rest of the calipers. With the rest, I totally skipped the second coat. I laid one thick coat and waited for about 8 hours before I installed the ant-rattle spring (which I also painted). The calipers turned out great considering the lack of proper prep and the rushed painting. The coating is uniformly thick and shiny. I will keep an eye on it for durability. I have over 90% of the can left so if results don't last I will do a better job next time.

I have used the original POR -15 many many times and have been impressed everytime. The calipers I am replacing was finished with the black POR-15 and is still great. Right out of the can, the consistency is nothing like the smoothness of the black version. It is pretty thick.
This silver caliper paint however is by far the worst paint I have ever used. The calipers were removed, cleaned with brake cleaner, wire brushed, degreased many times, cleaned with lacquer thinner, soap and water, and even treated with Metal Ready. The brake caliper are aluminum Brembo. Brushing it on it is streaky with all the brush lines. By the time i was able to get a foam brush ready and tried to smooth it, it was getting clumpy. On the next caliper I just used the foam brush and it was better but coverage was very uneven. It may be due to the rigidness of the foam brush vs a bristle brush. Even on the second coat the uneveness continued... probably due to the shape of the foam brush vs the caliper pushing uneven pressures. Even drying times are ridiculous long. Usually, here in Austin, Texas it take just a few hours. 12 hours later while handling for the second coat, the silver is rubbing off, undoing parts of the first coat.

I think the issue is that the silver paint has a high suspension of metals in it. The high solids content keeps the paint from flowing well and self leveling.

Basically I have wasted my money as well as countless hours of preparation and painting, and now have to strip and sand a mess and start over with a different product. If you are trying to get a smooth silver finish, do not mess with this. If your part has a texture you can probably get it to work. If you have the ability to spray this, you might be able to get it to work to be smoother.

Hi, I purchased this POR-15 brake caliper paint, hoping a to achieve a glossy, bright silver finish for the brake calipers on my Ford Mustang GT. I sanded and cleaned the brake calipers and brackets thoroughly, using the recommended cleaners and methods. The paint looks great, but is absolutely not glossy at all. I took another look at other reviews of the silver paint. There was another person who had the same results as I did - not glossy. However, looking at the reviews and pictures of other POR-15 caliper paint colors, I noticed they were very glossy and looked great. After waiting a few days to dry, the paint still seemed soft and very easily scraped away with my fingernail. I'm super disappointed because I have had great experiences with POR-15 products in the past. I had to completely strip my calipers and brackets back to the bare metal and paint them with a different product.

Color wise the product is a nice blue and similar to BMW blue they use for their brakes. I'd used the Duplicolor before with good results and it held up great for a decade but not available in blue so I tried this. The paint does not cure to a hard finish as I expected and the paint can be scratched off easily. Honestly, spray paint is likely just as durable so big disappointment given the POR reputation for quality. I thought it might harden with some heat from brakes getting hot but no and I even removed the brackets and those were cleaned to perfection and baked afterward and that didn't help. I would have tried the G2 knowing what I know now or maybe even the Duplicolor spray I found in Blue after ordering this. Having seen bad reviews on Duplicolor before but having an excellent experience I figured any complaints were likely due to lazy prep but that was definitely not the issue in my case.

I put this on the calipers of my new car. Since I only had a day to do it I really didn't have time to do the elaborate and proper paint-cure-repaint routine. I just cleaned the calipers with sand paper, wire brush, and caliper cleaner. Then I went to work with the paint. I brushed the first coat on, waited 10 minutes, and put another generous coat on until the metal underneath is no longer showing. When the 2nd coat was put on, the surface was full of brush marks and I was worried it it would dry like that. Then 10 minutes later I turn to look; the surface was smooth and shiny! The self leveling effect is true. After half a day of work I got pretty satisfactory result. 24 hours later I check the calipers and the paint has dried to a very nice hard surface. It has the wonderful thick, metalic feel to it as if the calipers are made of the metal in the paint color. I am sure if I had the time and patience to go through the full process the result would probably be even more impressive. But for something that would mostly be behind the wheels instead of being looked at closely, I am extremely happy with the result. I don't need them to be like Picasso's painting.
