Pontoon Boat Cleaning Tips
The following post actually comes from our friend Bryan Hermann from www.ezfender.com, who shared this tale of tube polishing and protecting on the Pontoon Forums website, and it was so detailed we figured we’d share. Thanks Bryan!
For those who are interested in polishing and protecting the tubes on your pontoon boat, here is a list of materials and step by step process to make your tubes shine like a mirror.
Start out getting the right tools and supplies.
I bought 2 quarts of Sharkhide Protectant http://www.sharkhide.com/index.html, 2 quarts of Cleaner and 1 can of polish. This ended up being more than enough to do 2 boats, actually.
I used my 8″ 3000 to 8000 RPM Sander/ Polisher and 5 buffing pads
-1 gallon of Lacquer thinner
-About 2 dozen old cotton rags and 1 roll of paper towels
-600 and 1000 grit wet/dry sandpaper to sand out scratches
-1 brass chisel and a small dead blow hammer to knock of welding slag.
-Masking tape, I used 2″ wide
-Plastic to cover the trailer
1. Start out by removing any prior protectant by washing the pontoons off with lacquer thinner poured into a rag. If any protectant is on, you’ll see it dissolve. Get it all off, or the Cleaner won’t attack the aluminum, which is what you want it to do.
2. Next, when drying the pontoon off you can feel any slag which was splattered on the pontoon during the welding process. Remove this with a soft tap on a chisel with a hammer I could even just use my hand in most cases. Wet sand the rest off and any scratches you want to remove. In my case, it was the bad scratches down the center of my pontoons from the previous owners docking technique. I don’t think he had one!
3. Dry again. Then tape of all areas you are not going to treat and cover the trailer with plastic sheeting to protect them from the acid and polishing compound.
4. Get ready to clean…Dilute the Sharkhide Cleaner to strength needed. I diluted mine 3 parts water to 1 part cleaner in a garden sprayer or spray bottle. Spray on the cleaner, evenly, let it foam up. After about 3 minutes of working time, I rinsed it off with water. This left behind a nice white finish that will let the polishing compound do its job more easily.
5. Polish time! Working in about a 3 foot section, I started at the top of the pontoon and worked my way down in an S shape to the masking tape line at the trailer bunk. Clean excess compound from the pad when it builds up and starts to bite hard. Add more compound to the pontoon when it seems like it does not bite any more. You want it to bite into the aluminum to work properly. Clean the pontoon as you finish up each section with lacquer thinner. Go to the next section and repeat all the steps until you are done with that pontoon.
6. After the polishing is complete, wash the pontoon off with lacquer thinner to remove all residue left from the compound. Make sure you remove it all. Use white rags or paper towels and clean until you get no black residue on the rags. If the tube is not completely free of residue the Sharkhide will not stick to the aluminum.
7. After you are done, it is time to apply the Protectant. It does not take much! Use a clean rag and fold it to the size of your palm. Pour a little Protectant to the front of the rag and wipe it on the tube in 6 foot sections. I found that working in a right to left motion from top to bottom worked the best for me. I did miss a few small spots, but after the first coat cures, in about 24 to 36 hours, you apply the 2nd coat; you can catch all the spots, missed. Don’t try to apply to missed spots when it is still wet, it will dissolve the first application and look splotchy. After the second coat is on, you can either stop there or apply a third.
