I've painted my upper crankcase with VHT Very High Temp Primer (VHT SP100). The can says to heat up to 250F for 30, then 400F for 30, then 600F (like my oven will go that damn high) for 30. This Primer is really for headers, not engine blocks & heads.
There is a caution that states not to exceed the heat tolerance of the least heat tolerant part.
What might that be for upper case aluminum?
I recall when heating up cylinder head in oven to remove valve guides that I was not to exceed 200-225F or something like that.
My top coats will be VHT SP995, which only has me heating up to 200F for an hour.
What is maximum(conventional) oven temp that I should go with my upper case?
My case is stripped down except for engine studs and the pressed bearing that the gear shifter drum fits into.
Thanks.
