That silicone residue BS is just that....BS. RV forum nonsense.
I have a 700+ square square foot garage with a leaking metal roof that you are more than welcome to come over and show me just how easy it is to remove silicone without residue so I can apply something that lasts a lot longer than silicone without leaking.
Silicone caulking on anything that you hold near and dear to your heart in the hopes that it will never leak is a pipe dream.
There is at a min of 400 linear feet of silicone garbage you can "erase" with your name reserved on it if you want a real challenge. To win the challenge, you must complete the removal in less than 8 hrs, use no chemicals and it must be 100% silicone free.. The panels are 2ft wide so there is lots and lots of seams for you to clean..
The only thing I found that works is to completely bridge the silicone with a 6" wide self sticking rubber roofing membrane.
My only other choice would to be rip up the entire roof and start over with fresh steel at the cost of $10K at now days pricing.
Once silicone decides to become unstuck in random places, you can not ever get it to reseal, new silicone does not stick to old silicone, no other caulk, paint or even tar will stick to it.
And by the way, you believed a RV "factory rep"? Yeah, you are gullible. Every RV on this earth is built using cheap Butyl rubber caulking for things like doors, windows and trim.. All told at a cost of at the most $10 for the entire RV.
