rustoleum, converter, what? before welding patch panels in?

[plugugly]

Im replacing some small sections of flooring that had begun rusting. Its right where the floor steps up and flattens out in front of the back seat. Where the 1/2 bolts are along the floor, that secure the floor to the underside bracing. I have cut out to decent metal, but there is still some discoloration of the metal as it is not smooth underneath. Ive wire wheeled it the best I can. before welding the patch piece on I was going to cover the metal underneath with something, paint, converter, something.

Any recommendations on what to use to help prevent rusting in the future?

brush/grind, clean, rust converter of your liking. Then prime/paint, paint, or coat depending on what product you want to use. Follow the directions for any products used in both sentences mentioned previously.

I like Ospho as a rust converter. Look up rust converters, read up on them here and the web....and take your pick. They work really well.

so a weld through primer wont be sufficient? upol weld2 or something similar?

I used some 3m weld through primer. Depends on the area, generally paint the majority with your favorite flavor of paint, then paint around the area you're welding on with weld through primer.
