Metal to metal body panels, what do you put in between?
 

Wanted to ask you guys who have done this before. I'm putting the tooltray/ rear floor in the rear of my 36 coupe. There is a steel brace that goes on the inside behind where the spare tire mount would go on the outside, and it touches the backside of the sheet metal on the inside of the coupe back. I'm wondering what you guys use for metal to metal contact between parts?

Body welting? 3M windshield sealant? Body sealant? Combinations of these?

It needs to be decently thick in consistency, not runny. I guess I'm concerned about expansion/contraction rates with heat and cold with respect to the paint on the outside, so maybe just welting is the ticket, or maybe I'm overthinking this!

do you need the brace now that your not using the spare tire holder?. if so maybe rubberized undercoating.
