Can powdercoating a water pump damage the pump?
I was about to do one for a friend and I called the manufactor of the pump and He stated he would not recommend heating it up to 400 deg. But that could be his option or for his pump/seal only. I didn't do it on that recomendation.
So if the pump can be disassembled, just make sure you tape up all area that should not be coated. (both inside and out). They also make High Temp Powder, but have not tried any of them. When I called Eastwood, they stated that the normal Powder can be used on engine parts wtih out problem..
Hope my .02's helped.
"Our standard thermoset powdercoat is baked at 400 degrees for 20 minutes, and can withstand somewhat higher temperatures than that once it's set - the name "thermoset" means that it melts once at a specific temperature, and then sets - not again melting unless much higher temps (600+) come into contact with the part."
