Rusting out storage bays

[atberger1]

Has anyone had a problem with their under storage bays rusting out? I have three where the floors have given way, These are cabinets where I typically stored heavier items. I went under the RV last weekend and coated all the other bays with POR15 so hopefully I will stop the rusting of the other cabinets. But now I need to find someone to do some welding for me.

I wish I would have addressed this sooner. I highly recommend the POR15. Bought it on Amazon at $45 per qt. Definitely buy the solvent as it is really difficult to get off your skin, You all may want to crawl under the coach and address any rusting going on as Gulfstream did not seem to rust proof the storage bays too well.
