What about body undercoating? This is what I thought it was designed for?
An oil pan will radiate some heat and cool the oil a bit, spraying on a thick insulating material will stop that cooling.
Yes, but the amount of cooling achieved (when it may actually be of some minor benefit on a 100deg day, working the engine like a dog, uphill, in a very hot engine compartment) is minuscule and won't be the difference between cooking oil or not. Especially in a 10-15 qt sump on a diesel pickup. That's alot of thermal mass.
If a flat piece of sheetmetal removed enough heat to be useful or if the cooling effect was relied on by design, the oil pans would be finned and likely aluminum.
Benefit outweighs the risk here many times over if it keeps the paint form getting chipped off and rust forming.
