Ideally, the substrate should be thoroughly preheated to the
highest temperature that the substrate will allow before oxidation.
This temperature should be maintained as constant as possible
throughout the whole spraying process.
All or most of the cooling wants to be directed at the coating and
not the substrate.
Hope that helps.
