when sanding hardwoods, the goal is usually the smoothest surface possible, but this is not the case when sanding an exterior deck surface. for sanding deck floorboards, use sandpapers with grits no rougher than 60 or 80. sanding with finer-grit papers 100-grit or above will smooth the wood to the point where the pores begin to close down, which will hinder the absorption of stain or sealer into the wood.
hey guys, i'm doing a light restore on an '85 ranger bass boat. i've read that the color can be brought back to life by wet sanding the gelcoat then compounding, polishing, and waxing. i started on it today and i'm a little disappointed. the surface is smoother, but there's not really any more color than before. i want to make sure i'm doing it
instead, hilton likes presta strata ultra cutting crème, which is a compound and polish in one. it removes oxidation, weathering, and swirls. moreover, its aggressive enough to remove wet-sanding scratches see fear of wet sanding, above left by sandpapers as rough as 1500 grit and still produces a high-gloss shine.

a sanding disk, held flat against the wood surface contacting the greatest possible surface area of the sanding disk will never cut as aggressively as a blade tool. a plane used on a stripper, will destroy the natural fair surface created by the wood strips.
re: can you sand aluminum? the boat's skin has a very thin pure aluminum coat over the alloy aluminum. i would not use anything stronger than scotch brite. aluminum rivets such as ad aircraft type can be found on the net. alodine is easy and will save much work down the line. a coat of zinc chromate and paint should work.

the boat is about 20 years old and in pretty good shape but it needs paint. the boat appears to have been painted a few times. the paint is scratched, dinged and peeling in a few places. i started by sanding with a palm sander and 80-grit paper but this did not do much.
wet sanding with waterproof sandpaper is often the best approach to sanding cured epoxy. wet sanding removes amine blush while you sand, reduces clogging of the sandpaper, and reduces dust and exposure to partially cured epoxy. it lets your sandpaper go farther and provides a visual clue that everything is properly sanded. however, if you have bare wood or wood that cannot get wet, you will need to dry sand.
sand between coats with fake steel wool by 3m - finest grade you can get. wet sand every second or 3rd coat with 400 grit. anything coarser is for paint salesmen. this will build coating thickness faster and still give you a good smooth paint job. do not use solvents of any kind to clean up after sanding.
no shortcuts for good prep work. sand with the grain. early coats are sanded with 180-220 grit paper, for later coats use 320-400-grit wet-or-dry paper. bear in mind that wet sanding is more aggressive. if you use a random orbit sander e.g. to remove lots of old and brittle varnish be very careful.

restoring nonskid decks. allow it to dry. lightly sand the surface using a random orbit sander loaded with 60-grit to level and scuff the old surface. finish with 120-grit, vacuum up any dust, and wipe down the surface with a rag and 202 fiberglass solvent wash, replacing the cloth as it picks up residue.
