Re: 1971 Winner Bimini 17' Tri Hull
In case there is any future interest in the steps I took, here they are:
1. I first tried sandblasting but then realized that this was making the pits worse.
2. Next I used a 24 grit roloc disk and lightly took down the high spots.
3. I then moved onto an 80 grit roloc disk to it as well then blew off with air nozzle.
4. I then applied the Bondo Glazing (spot) Putty with a plastic spreader making sure to work it into the pits.
5. Once the glazing putty has set (I waited 2 days), I hand sanded with 150 grit then blew off with the air nozzle.
6. Threw on a coating of Rustoleum Self Etching Primer.
7. Next day I sprayed on 2 coats of Rustoleum filler primer.
8. The following day I used a palm sander with 100 grit paper and sanded down a little bit and cleaned with the air nozzle.
9. Repeat step 7.
10. Repeat step8.
11. I then sprayed on 1 more coat of Rustoleum Filler Primer and let it cure.
12. I then sanded by hand with 150 then 220 grit sandpaper and blew off with air nozzle and wiped down with a clean dry rag.
13. I sprayed on 2 coats of Rustoleum Metallic spray paint and let this cure for a day.
14. I then lightly sanded with 400 grit sandpaper and sprayed on 2 more coats of Rustoleum Metallic spray paint and let it cure.
That's about it. Depending on the job done with the glazing putty and depth of the pits, you may need to throw on a few more coats of filler primer and sand a bit more.
