Opinion on Bilt Hamber rust treatments?

[Five_Star]

How do people rate the Bilt Hamber anti-corrosion treatments, specifically I’m looking at using either their Deox-GEL or the Hydrate 80 treatments on some rust pitting around the rear arches.

I’m concerned the edges of the arch lip at the top are quite thin and delicate so don’t really want to remove more material than I need, but at the same time would like to cure the rust before it gets any worse!

@jpaul the arch liner is a fabric type affair that removes fairly easily so should be no issue to see the full extent of the problem.

I was thinking that the epoxy might have improved impact resistance on the arch edge. I think I'll be going with the deox gel / electrox primer / epoxy top given peoples suggestions on here, very helpful
