Chassis Rails...!

[gsw500]

Just a thought i'm sure someone has probably thought of this before.
At present I have the engine out on my 500 and have a good view of the top of the main chassis rails.
On inspection there is an amount of rust but only in patches and looks to be surface,concentrated around where the manifolds run.
I'm replacing the heat shield material(other thread).
Now I'm wondering, would the heat from the manifolds be a factor in the deterioration of the chassis rails as it is only on the top nearest the manifolds.
Having rails shot blasted and then covered in POR15 would it be an advantage to cover these rails after in the heat barrier wrap you can use on hoses and manifolds or would this only trap the moisture.
Your thoughts...

Are you sure its not where water drips down the inner wing. I ran strips of closed cell rubber (like home door / window weather strip) along the top of the inner wing to channel water so it drained down the front near the rad, but away from the chassis.

moisture trap, don't do it...or wrasp the manifolds for the same reason.

Moisture trap for sure, just do your anti corrosion paint and that will do fine.
