Hey, this is off the wall, but has anyone ever tried applying household floor polish to the hull? Would the sun do bad things to it?

That is what everyone guesses. Obviously PoyGlow and VertGlass are just Mop'nGlow but we assume there are UV stabilizers added. Try it.

David, we used PoliGlo on our C22 and were very happy with the results. Be sure to follow the directions. It is not expensive enough to warrant you using a household product instead.

Thanks. after it warms up enough to pressure wash the hull, I'll try one of those.

...and just in case the household version is as we suspect, you'll be very sorry you saved a few dimes on it... as your boat turns amber and the stuff starts to crack and flake off. Some friends who added coats of Poly Glow for something over 10 years found that it started to yellow... I took the hint and removed mine (with Poly Prep) and started over after five years. Otherwise, the ease of application, durability and longevity are phenomenal.

BTW, don't just pressure wash... Make sure you scrub off every mark, or Poly Glow will immortalize it!

Should you pressure wash?

Poly Prep with a Scotch pad is recommended. No wax should remain, and every smudge should be gone. Poly Prep is powerful stuff--wear rubber gloves and/or use a scrubber on a stick.

My ulterior motive is this: no trailer. I'm looking for a product I can apply from the dock while the boat is in the water, if possible, to brighten up the hull and apply some water repellancy. Water draining off the deck seems to soak into the gel coat a little bit. Using Poly Pro and especially Poly Prep sounds like something best applied while on the hard.

Actually, I suspect Poly Glow would be easier from the dock than the rub-and-buff waxes and cleaners. You just wipe it on with their chamois-like applicator that you put on a broom handle. 4 coats does it--each coat is less streaky the the previous until you end up with an even shine. You can do one side of the boat in about an hour. Get the boot stripe too--it'll look nicer. Poly Prep will take off all old wax and most marks, and could also be done with a scrubber on a stick. Whatever smudges or marks remain will be amplified by the shine of the Poly Glow.

Should you prep the hull before or after you re-touch the ablative paint. I'm wondering what the run off of the poly prep and polyglow will do to the paint.

Poly Glow doesn't run off--it wipes on thinly and dries almost immediately. Poly Prep will run off as you hose it down, but I don't think it'll seriously deteriorate the paint. You could use a more benign cleaner--if it does the job. The main requirement is no wax.

When applying in the water be sure to have your first mate stand at the shrouds on the other side of the boat to make it easier.

Or if one's not available, swing your boom out over the water with the topping lift to support some sort of weight to do the same thing. I used to watch an old timer winch his mast down to about a 45° angle to the dock with a 4 part fall to scrub his boat's hull before each race. He'd tie off the near side close to the side of the dock, so the boat wouldn't drift into the far side when the keel was up. Pretty cool to watch, and didn't seem to affect his mast at all. Lighter boats than ours though, can't think of the make. Older 24' or so self-built plywood hulls...almost bought one at one time (recommended by this same guy). Hmmm...Alzheimer's setting in. Starts with an "A"...

For easier access to the hull, you can tie a long line onto the main halyard, walk about 4 slips over and heel the boat considerably. Then tie off the line to a handy cleat until you are done. Then repeat on the other side.
We did this last week to put a name on a Catalina 28 and I've also done it with a Starwind 27 - it does make the task much easier.
Just make sure that you ease the opposite side docklines first...

I know I will get some heat but why use non marine material and take a chance>? The difference in price is not that much, is it!

That's exactly what it was. I told you, Alzheimer's. No idea where the "starts with an A" came from. I guess Alzheimer's starts with one...

Fond memories of sailing under the stars in Nanaimo Harbour in a young ladie's absent father's Thunderbird.
Ahhhh thanx for the memories.

Ahem, yes use Marine specific wax.

I'm not trying to "save a few pennies" so much as I'm looking for something relatively easy to apply with along handle applicator from the dock so I don't have to haul out the boat. thanks for the tips everyone.

The link to that polsiher no longer works. Saw it before. Great idea for while the boat is in the water.
