POR-15 under body filler

[Ox65]

Has anybody try this. I think if I hit the POR-15 with some sandpaper, it sould be good to fill over. POR-15 is hard as a rock when its dry. What do you guys think.

I have used it on a pickup I own and it is a good cheap fix. But not always the right way to do things when quality is concerned. Eventually the rust will return and you'll have to deal with it again. If you do use it and you have some left over I recommend putting some wax paper between the lid and the top of the can. It'll help to extend its shelf life.
