Ok so I'm looking into redoing the floors with por 15 an rhino line the interior floor the underneath has already been done but I highly doubt they ever did the interior side of the floor. I do have one spot of rot building up that will need to be cut out an patched up has anyone done it to there cars an how great does the por 15 or rhino liner work I do live in new England (Ma) to be exact. roads here do get really salty an wet, that's how my 89 gta got ruined along the rockers, an frame rails

 

Sounds like it should work good. The one member I believe he lived in England sprayed it on underneath but I think it takes a special gun.

 

See what I was gonna do I buy the big tub of it an use a paint brush to lay it out of course remove all surface rust first I was gonna do from the top of the toe board all the way back to the trunk well should make it rust free then I'll have a rust free third gen that will last for ages to come

 

Maybe even touch up the bad areas first with some good paint.

 

If you're going to go that far with the POR and bedliner, you might as well go a little further and do the wheel wells and along the frame sections up front, inside the trunk well and back in behind the quarter panels. If you haven't already done the wheel wells, get the rubber crap off with a wire brush on a grinder and do the same there as well.
