Heat treating paint on waterpump housing..???
 

Well I am currently heat treating my pulleys, nuts and bolts, and misc stuff (all black) duplicolor ceramic black.... I have the water pump housing (everything) painted black, I am a very cautious guy, and was wandering if it might be a bad idea to put it in my oven at 300 degrees or if I should just lightly use my heat gun (tiring) on it like I plan on doing when I treat my engine block.

BTW I used the aluminum 1200 duplicolor ceramic for my lower intake, and boy does it look good, I think Im going to paint the rotor housings aluminum now with all of the iron being painted black, it will be easier to clean this way :)

anyone?

I don't think it would be a problem to bake it at 300 degrees.

thanks

I much better prefer powder coating to paint. I know this is not always an option from everyone. One tip I can pass along on the heat. Do what us powder coaters do. After removing old paint and rust from the part, "out gas" the part in an old oven. The oven can not be used for food after this process. Put the part in the oven and bring it up to the desired temperature. For powder coating this temp is about 400 degrees F. Leave it at this temp for 20 minutes. This will open up the pours in the metal and any gas/oil ext will come out. Then remove the part and clean with paint thinner. If the part was not "out gassed", then there is the possibility of having pin holes in the paint/powder coating when the part is being baked with the paint. I hope this makes since.

I would also do a test to make sure the paint can take the heat.

I recently found a good website about heat treating
