I used G2 brush on red and was very happy with the results. Decently priced and comes with everything you need.

Do you perhaps have some photos of the results? I'd like to see as well.

I brushed mine with G2 gloss black, been on for about a year and a half now. End results look good and seem to hold up well. Make sure you clean the calipers off good with a wire brush beforehand and mask everything you don't want paint on, especially the rotor. Paint spreads very well and the brush marks disappear after a few seconds. Need to wait a while before driving it so beware.

I tried the g2 brush on and I am assuming I had some bad paint because it did not come out well. I sand blasted them to bare metal and used the vht caliper paint. Looks amazing and after 2 years still looks great. If you are taking off the calipers then I would reccomend the spray vht. The g2 is very good if just painting while on the car and taping off thing.

Bought G2 in gold 7 years ago have re-coated/touched-up once since. Very pleased. It does have a use before date on it so make sure if ordering on internet to add a note to the order not to ship if the date doesn't meet your intent to apply date.

Whats the difference if I used High Temp Engine paint ? I mean besides being a spray? Can I just use brake cleaner and a scrub brush, followed by the engine paint ? I was thinking to take the time and tape and foil off area to protect other areas and spray while on car. Seems about same time in the end. I think I will have better finish with spray vs brush . Any thoughts ? Just trying to cut costs.

I did that on my last car and won't ever again. The spray isn't very "thick" and shows all the imperfections of the casting. It also doesn't adhere as well and after a year or so needed to be completely redone. Do it right once with the brush and be done with it.

What temperature setting?

You have any trouble with new seals leaking after reassembly? I'm assuming you took them apart for the roasting operation....

Edit: Aren't you concerned about the vapors depositing themselves within and ruining the oven??? o.O Or is it literally an old oven used for only that......

I think it was about 200f (can has the number on it )

Really not much drama at those temps and yes, the oven in the Kitchen.

Not sure what you are asking about the sealing afterwards?

I reseal race car calipers all the time and other than they have no dust boots, the operation is the same , whether the housings have been re coated or not

Well, I've been told that removing the piston and then afterwards installing new seals can end up leaking without re-machining the cylinder bore. It wasn't spelt out as a guarantee, but a risk.

You might want to clarify that with who ever told you that.

99.9% of calipers, the caliper bore does no sealing, just supports the piston.

The seal groove seals to the stationary seal.
The piston finish is the only real important surface as it is the sliding sealing point.

The only caliper that comes to mind the the bore condition is critical is 1963-80ish corvette, old JL8 Camaro
This because the seal slid in the bore ( think it was a Girling patent work around? )

I never meant to suggest that the bore did any sealing.... I'm not sure why he mentioned the machining part, but he backed off of it as a remark to discourage me from replacing seals. So I pressed further (just now again).

His experience in the shop was that they'd come back after remanufacturing much more often than they did with new (or factory reconditioned) calipers. He didn't know specifically why, but he said it may have something to do with the overall match of a new piston whether the aftermarket piston says it is speced right or not. It could be differences in metal expansions differ depending on the quality of the metal. He didn't recommend reusing the old piston.

It was an educated guess, but his experience lead me to be concerned....

So I was curious as to what you thought about that.

After looking at tons of photos of painted calipers on Silver car. I decided it takes away from the car in my case. Its a fine line between clean and simple and clutter looking. I know you guys understand. The guy who accessorizes too much . People looking at the car, focus on the accessories and not the car. I was going to go with that Kyne v1 front lip too, but same thing. It starts to look cartoonish. Ha, I will just spend my money on painting 2 chips / gouges I have on my rear bumper. I had a friend try to convince me to black out the hood scoop inserts, . I explained my views on that . Ahhhh, I hate this disease called customizing, it occupies my brain !

I think he was talking of the " seals " with in the caliper vs sealing it with a coating.

I might be wrong, but thats what I get .
