Boat Polish and Boat Compound Products

How do I wax and polish my fiberglass boat? 

Boats should be polished and/or waxed when they are out of the water, so you’ll likely be conducting the job when your boat in on a trailer or storage pad. Additionally, make sure you can freely move around all sides of the boat.

Before you do anything to your boat’s exterior, you need to first clean it. We recommend using lots of fresh water and soap intended for marine use. If you are in a saltwater environment, you will want to be sure that all salt is removed as it can interfere and break down boat wax and boat polish products.

Also, be aware that salt is good at hiding in any cracks and crevices as well as overhangs such as T-Tops and/or hardtops. After a good lathering, make sure to give a thorough rinse using clean fresh water and a reasonable amount of water pressure. After you’ve finished cleaning off the salt and surface dirt, you can begin the compounding and waxing process.

If your boat has any removable fittings, remove them. Removing fittings will help to prevent your buffer from getting caught. It can also be pretty tedious trying to hand wax around fittings. Of course, when you remove fitting make sure that you organize your hardware effectively so that reassembly is easy.

It is not necessary to polish your boat every time you wax it, but you will want to polish it anytime the finish looks dull, faded, pitted, or scratched. When polishing your boat, start at the back and work your way towards the bow.

When polishing your boat:

• You have the option to apply the polish using a buffer or by hand
• Use circular motions to avoid streaks
• Work in 2-foot sections
• Buff until the surface looks glassy
• Before waxing, rinse the boat to remove dust

Apply the wax either by hand or electric buffer using circular motions much in the same way you applied the polish. Wait until the wax is hazy, indicating that it is dry. Then buff the wax until it shines using a soft towel.

Should I use an electric polisher to polish my boat?

When you’re ready to begin compounding, you will need to use a variable speed polisher to obtain the best results. Wax can be applied by hand or by using a variable speed polisher on the lowest possible speed. Check out the Shurhold Polisher and Polisher Starter Kit below to help with all of your polishing and waxing needs.
