I just read a poster asking about a rusty floor and all the responses were about using POR.
Doesn't anyone use Ospho any more? Why not? Thanks.

Ospho comes in rust remover, and rust converter applications. The POR-15 is "more" like the rust converter, but is used to seal the rust primarily; that and to build up weakened, rusted, pitted metal (think along the lines of a fiberglass resin). Without a rust converter, rust continues to do it's damage. POR-15 is also used to prevent rust, by being a barrier to moister. With the nephews 51 Bus Coupe, we used a fiberglass resin, and 1/8" thick rayon type matting to strengthen his pitted floors. Hard as a rock, and solid now, and he's painted the entire floor in red primer. Better than the chicken wire and roofing sealant I found in one car I bought many years ago (63 Ranchero).

ok, Thanks

The best rust proofer I've found is Etching Primer over bare metal. I think a lot of new car Mgfrs. still use and recommend this process, although even some good restorers will argue for epoxy primer over bare metal. oh well


Enjoyed your bio. Got any posted pics of your SD

Ron, ospho is the brand name for phosphoric acid. I just bought a gallon jug from Home Depot but it was under a different brand name. Just ask for phosphoric acid in the paint department in Home Depot. Tom

Ospho, is great stuff, just be sure and ware rubber gloves and some eye protection. First time I used it about 25 years ago I was working on a 36 Ford sprayed the under side of the car with it. Where ever it dripped on the concrete floor it ate the concrete up. Be careful with it. burns the hell out of skin. Ask me how I know. Good luck Mike
