G2 Caliper Paint is awesome! It’s a super hard epoxy that resists chipping and fading. My calipers looked freshly painted years later. Some additional tips from my experience with G2USA Caliper Paint: 1) It’s a two part epoxy with limited use time once it has been mixed. So it’s best to have car up on four jack stands with all wheels removed. Could run out of time if trying to do two at a time. 2) The ambient air temperature during painting MUST be in the range of 56-70°F (13-20°C) to spread G2 properly. If air temperature gets a few degrees higher it begins to get gloppy on the brush and turns into a mess. It’s fine if the air temperature gets higher when it’s drying, that actually helps the surface to level out and remove any brush marks. Tip for summer painting: Put the car in the air and do all of the prep work the day before. Then early the next morning when air temperature is in the painting range, spray them down with brake cleaner to remove any overnight dust or moisture. Then paint. 3) Only one brush is included in the G2 kit. Better to buy more to have others help paint or if you drop your brush. Harbor Freight sells a pack of 36 silver handled acid brushes for $2.99, SKU 61880 4) The latest non-chlorinated brake cleaner does a very poor job of actually removing baked on brake dust and dirt. Plus one can isn’t enough. Buy several cans of cheap no name brand brake cleaner at Walmart. Also buy cheap nylon brushes or even use an old toothbrush. A cheap plastic oil drain pan for underneath while you are cleaning is a necessity because all that nasty junk that comes off the calipers will stain driveways and garage floors. 5) Formula409 is absolutely the best for cleaning brakes. Haven’t found any other cleaner that works as well. Spray tons of Formula 409 as you brush the calipers. Keep spraying. It will foam up and lift the brake dust and dirt. Keep spraying. Then use the brake cleaner to rinse it off. And repeat as necessary. Remember that only the visible areas of the caliper need to be cleaned and painted. The backside is like the backside of the moon. No one ever sees it. 6) Now is the time to sand any rough areas on the calipers. Sanding sponges in various grits work well for this. Start with roughest grit and work towards smoothest grit. Spraying Formula 409 and using it as a wet sanding lubricant works well. Grey calipers can have rough spots in the casting. Blue calipers often have chips in the paint that could show through. Sanding the surface makes for a better result. Always spray down with brake cleaner after sanding. 7) Tape out any areas that you don’t want to accidentally hit with the brush, like bleed screws and their threads. 8) Wear a high quality painter’s mask like an N95 with the one way valve that makes it easier to breathe out. The epoxy fumes can really hit you you, even when painting outside. 9) Mix G2 according to instructions. Many thin coats will give the best results. One person will have to move fast around the car to try to paint all four themselves with many coats so there is a tendency to apply heavier coats. It’s best to have two people each painting two calipers and go back and forth keeping coats light. No rush to put the wheels back on. I let mine dry overnight just to be safe. The more time you give epoxy to cure the harder it gets. 10) There are many places on the Internet to buy brake caliper stickers. I got my Brembo stickers from a guy who I often recommend. He made me up sheets in several sizes because I wasn’t exactly sure what size would look best until I had them in hand. His business contact text/call is Scott at 954-266-8233 Good luck! Hope these tips help!
No foam brush is messier. And you have a limited amount of mixed epoxy. You don’t want a brush that soaks up/wastes a lot of it. Use the brush that came with the kit and the Harbor Freight silver handled acid brushes. Part number is in my comment
How come the link you guys provided doesn’t have Blue paint as an option but other G2 paint sellers do? Not having blue paint available on a BMW channel is wild to me…

Lovely writeup mate, God bless
Would it be fine to paint in 40-50 degree weather?
Used a kit from Foliatec to paint my f31 calipers. Still looks like new after 3 years, even with the harsh winters in Scandinavia.
One kit is enough for all 4 brakes?
Great, quick to the point video. I wonder if using a foam brush would keep the brush texture from showing up?
No foam brush is messier. And you have a limited amount of mixed epoxy. You don’t want a brush that soaks up/wastes a lot of it. Use the brush that came with the kit and the Harbor Freight silver handled acid brushes. Part number is in my comment
Yeah use the same kit been on my car for 4 years no issue at all
Can you get M stickers like the ones you had for Porsche?
Brake spray paint works much better. Just takes more work. But you won’t see any marks. Just a smooth finish all around
Actually if ya take your time this paint works wayyyyy better and last way longer than spray paint
Love the red calipers behind the bronze wheels. Great choice, Gary!
Prep work is critical. Nicely done!
Looks good did this on my last car now time for the f30
I'm pretty sure you can get calliper specific spray paint if you don't like the texture the brush leaves
The factory original brakes on my car came with yellow calipers and PCCB brakes. It stops well.
How does brush compare to spray? Is it good enough?
One kit will be enough for all 4 brakes??
Depends on how big your brakes are. For these larger Porsche brakes we needed 1 and a half kits
Wow I’m gonna need this!

Instructions weren't clear enough, I got a CEL
G2 is gd stuff
Lit.
That orange peel look on the yellow looked atrocious.
