Thank you to KP for the idea about the Rustoleum Hammered Paint. I just did an old resin table that had a large burn mark in it. It came out great. I did learn that you get the best hammered effect by spaying a fairly heavy coat. I put on two light coats and waited two days for it to fully dry. I could still see some uneven streaks in the finish. I then put on a heavy third coat. That did the trick. The final finish is a trued hammered look with a very nice charcoal black color. Goes great with the black kettle on a Performer. No streaking after third coat. I ended up using most of two cans to get the desired look. Looks like a professional job now. No need to buy a new metal top. Did the hubcaps on the wheels too.
For surface prep I just scrubbed the table with a kitchen cleanser, wiped down with a solvent and then did a very light sanding with a 600 grit sandpaper. I would have used 400 but I was out of it. Sanding was to aid in paint adhesion. Final step was to wipe with damp rag to pick up any dust from sanding. Prep took about 45 minutes or less. It was a hot day here, so all the fluids dried very quickly in the hot sun. I seemed to get very good adhesion with the paint. It will be interesting to see how well the paint holds up with use. I am expecting it will do well as it seems to be hard enamel.
