Don't you HATE rusty paint cans? Especially when they're almost full of perfectly good paint or polyurethane? I was confronted by such a thing last week. If the can would have been almost empty, I could see (maybe) disposing of it and buying new, but this can, as you can see, was nearly full. To salvage the contents, here's what I did:
First I stuck painter's tape into the inside of the rim.
Then I poured the poly into a new can I picked up at my local hardware store.
- To help prevent rusting of the new can, stick painter's tape onto the rim and draw your brush out along that edge.
- If rust flakes off and into the paint/poly, you can actually strain it using an old pair of nylons or cotton cloth as you pour it onto your new rust-free can.
