Chevy or Ford, Sounds like a couple of kids in a sandbox. Lets have an adult conversation and learn something.
Well since you asked so politely, yes you and Rusty can come out of the sandbox and join us for that adult conversation, promise you will learn something.
Chill, life is too short.
Oh, Ford.

The OP's original question was about PT's Eternabond construction. RV Guy gave us all a very good fact based lesson on PT's production methods and construction materials.
Let's just leave it at that, unless you have some additional info on PT's construction.
What I see is no matter how much proof you have there are people stuck in there ways and they dont like change. I say do the reserch and you find out for yourself then come back with results.
