Temp of hub?

So I have been doing a upgrade of the rear brakes to the SVT brakes. as seen below:


The picture is old, the caliper is also red now...

The question is, I painted the face of the hub. The non-vented rotor's center "cap" comes into direct contact with this surface. but it is also sandwiched by the rim. The paint is POR-15 so can handle hot temps. Does anyone think I am going to run into problems doing this once I get the rotors on and they heat up from track use braking?

Rotors may end up stuck to the paint, or have paint come off with them when removed.

I always "paint" that area (especially the hub center) with a bit of never-seize to reduce corrosion. Outside on disc gets more, 'cause of the dissimilar metals issue with the Aluminum rims.

I'd guess the worst would be some clean up the next time the rotors come off. Not a good area to paint IMHO, but as long as they're together & working OK you could just wait & see what happens - paint'll be easier to get off if the heat loosens it!

Moving this to the new "Brakes, Suspension & Chassis" section, Wheels & Tires just got split off to spread things out a bit.

Was wondering this as well since I will be painting my stuff soon as well. Guess worst case the paint comes off. Could always put a little grease on the painted hub face before putting wheels on.


Just noticed this new section :)

The surface is a register surface for running flatness of wheel, anything you put there that turns solid is incorrect.

Well we will see how it works out. The Por-15 is self leveling so its not like there are gobs or stuff or higher build up in other areas. The thickness is no more that the rust build up that came off when wire wheeled. I made sure there was minimal thickness on the hub (mostly dry brushed) along with only using 1 coat.
