How can I fix pinholes in floor

[yarbroughbs]

I had the tub on my 71 blasted last spring. Since then I have replaced the big rust holes in the floor. I have many pinholes and places that I missed with the welder(New 2 welding). What is the best way to fix the pinholes without having to start over? I plan to cover with line-x and boat carpet when done.

Make sure the holes are painted inside and out, and use some brush on seam sealer. Will seal it righ up. Honestly though if the wholes are small enough, the bed liner can fill it righ in, but then it can create an entry point for water to sit under it and rust out the floor.
