Hello, I painted my brake calipers using XTC Primer and XTC Paint. I need to bake them in the oven now to cure the paint. Do you know if it's safe for the pistons, rubber seals, grease etc.. in the calipers to be exposed to such high temperatures? I'm worried that 350F for 30min could damage the piston seals. Thanks.

To add to my question, can I achieve the same curing results at a lower oven temperature/longer heat cycle?

Okay, so I went ahead and put the calipers in the oven at 200 F for 30min just to be on the safe side. Everthing seems fine, but I know that's not hot enough for the resins to reach their full hardness. I'm thinking of baking them again at 250 F this time for another 30min. Do you think this will be enough to get a full cure?

To cure (XTC) Xtreme on an exhaust manifold still on a vehicle, I bring the motor up to temperature, leave it running for 40 minutes and then let cool to room temperature to cure. Based on that, with the multiple heating cycles you suggest, let it bake for 40 minutes and you should be fine.

Eddy's suggestion is spot on. If you bake the calipers at as close as you can get to 350 degrees Fahrenheit for 30 minutes, the XTC will reach a full cure once your piece gets back to room temperature after being baked.
