Gary,
I recently re-surfaced the tub and adjacent wall in our 61 Tradewind. I
used Bondo Auto filler for the hairline ( and not so hairline) cracks,
sanded and then sprayed three cans of auto paint over the tub and wall,
actuall it wasn't auto paint although I got it from our local auto store, it
was an enamel spray especially formulated for many common outdoor materials
(primarily plastic, wood, metal). I taped sheets of news paper over the
surrounding walls and did it before the floor was laid. I had very little
overspray and with a dust sheet taped up you'd really be able to control it.
It looks brand new and has stood up to the last three weeks beach camping
very well, no chips from dropping the shampoo or scratches from the three
tons of sand we carry in each day.
I can e-mail pics if you want to see the result.
Good luck,
