If you do not have any coatings at all on the bottom of the boat, we suggest to sand the hull with 80 grit and then apply Tuff Stuff High Build Epoxy. It is a water tight barrier coat designed for use under the waterline and with aluminum hulls. Use 2 coats. You can apply the 2nd coat within a couple of hours of the first coat. (up to 6 days)
After you apply Tuff Stuff marine epoxy primeron hull, be sure to use an aluminum safe bottom paint. The bottom paint needs to be applied the same day as the Tuff Stuff marine epoxy primer. Bottom paints in general are designed to repel hard growth. Smart Solution is an excellent bottom paint for aluminum hulls when in salt water. We recommend Mission Bayfor fresh water. I have listed links below to the products described above. These can be brushed, sprayed, or rolled. If you already have coating(s) on the hull, pressure wash, sand with 80 grit, and then apply Smart Solution.
Gelcoat Restoration Guide
Keep your gelcoat in good condition by using these 4 steps:
As you haul your boat out of storage you may want to get the gelcoat shining once again. Use the steps below as needed:
A one step clean-and-wax products combine washing and waxing in one step, best used on new boats where the finish is in good condition with little or no oxidation, try 3M Marine Cleaner and Wax.
Light gel coat oxidation? Best to use the least aggressive method if possible to prolong the life of gelcoat Clean with 3M Marine Boat Soapand buff with the 3M Imperial Compound. Avoid direct sunlight and room temperature is best. Use a tape, like 3M 471available in different lengths.
Step 1: Boats that need more aggressive cleaning just wash surface and remove loose contaminants: Use a non-abrasive light detergent to remove all surface dirt and all previously applied coatings, 3M Marine Boat Soapor Marine Clean are ideal.
Sometimes you need something stronger to remove surface rust, oil, tar, algae discoloration, black streaks caused from water runoff, exhaust and waterline scum or other stains before waxing or you’ll seal in the stain. Usually you will need an acid-based stain remover like Hammerhead Hull Cleaneror Hull Cleaner, Extra Strong by Tip Top Teak (test in an inconspicuous area first) using gloves.
Step 2: If your boat is a bit more oxidized a rubbing compound (liquid abrasive which “sands” your hull) is needed but do so carefully as you can rub through the gelcoat. The more faded your hull the more compounding you’ll need. The 3M Imperial Compound, usually applied with a polisher if possible and compatible 3M pads,like the white 100% wool pad,is recommended by 3M. Keep product off bottom paint, if applicable, by taping off as it can spatter. If the compound isn’t strong enough for your level of oxidation and scratches then you may need to “pretreat” with a 1200 (or 800) grit as needed prior to the compound.
