very fine technique on those coatings.
If one doesnt want to do the very very thin coatings on a hot hot grill,
after the first thin coating and heat , let the surface cool , then apply the next thin coating
and heat up until cured. cool down , and repeap
this takes quite a bit longer , heat , cool . heat
but you dont have to hurry so much evening out the oil each time.
Thin is key. the thinner the better.
