Wax on, Wax off
Well, Daniel-San, welcome to Wax Philosophies 101! Actually, you are doing just about all that can be done and since you are obviously not burning the paint off with your buffer, you're using that correctly, too.Basically wax is used not to just make things shiny and for water to bead up. It actually seals, albeit temporarily, the porousity that naturally occurs with gelcoats, fiberglas and paint as it ages. Maintaining good wax is key in the longevity of your paint. Now, wax is not a panoceia for what might be wrong with the surface; in other words, wax won't make up for bad paint or surfaces. It just helps seal the porousity, keeps dirt out and helps protect. Armour-All is also good for hulls, but it can make decks dangerously slippery so I'd advise against that.Good wax doesn't have to be expensive wax, so just about any quality wax is as good as another. For maintenance, you could use one of those spray-on, drip-dry formulas that you see all the time. You should, actually, wax the deck and coach house, but be aware that you are creating a somewhat slippery condition here on the deck, so you need to be aware of that, wear good rubber-soled deck shoes and alway remember, one hand for you, one hand for the boat.For buffing out oxidation, I would recommend any of 3M's products especially some of their commercial products available at most automotive supply houses. 3M makes a series of liquid buffing compounds; 3M Filling Glaze, 3M Polishing Glaze, 3M Finishing Glaze...all with corresponding grits. I would recommend 3M Polishing or Finishing Glaze. You can also buy what amounts to Polishing Glaze at most marine centers. It's in the same area usually as the product you are now using, but comes in a quasi-clear plastic bottle with a light brown liquid inside, calling itself 3M Heavy Duty Polishing something or another. You can't miss it. It's good stuff and does better than the bottle you are now using, but contains NO wax.I'd continue using the buffer. I hear arguments about this all the time, but I have a 30-foot boat and I would like to be able to use my arms after the annual buff-out, so I use a buffer as well. Keep the pad damp for application and then use a clean, dry one for removing the material.I think you are on the right track, so press on.
