Boat Wax, Boat Polish – Which Products Are Best for a Fiberglass Boat?
While often overlooked, performing routine fiberglass hull maintenance is necessary to maintain and restore fiberglass shine. Regularly cleaning and protecting your boat’s exterior will keep your investment looking newer longer. But, when you look across the marine industry, there are so many boat wax and boat polish options – which ones are the best?
However, before you start, we like to share some recommended steps.
5 Steps for Polishing and Waxing Fiberglass Boats
1. Secure Boat Out of the Water
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.
2. Wash Your Boat
Before you do anything to your boat’s exterior, you need to first clean it. We recommend using lots of fresh water and a 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.

3. Remove Fittings
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.
4. Polish Your Boat
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
5. Wax Your Boat
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.
An Electric Polisher Makes the Job Easier
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 o

great list. I have bought an old boat that needed polished and this article gave me a lot of choices.
I just purchased a Ranger Bass Boat. It has small scratches on the hull. I need to purchase a good buffer, wax & compound to remove the scratches. What would you recommend that I use?
Al,
Congratulations on your new Ranger Bass Boat! To remove small scratches from the hull and keep your boat looking great, you’ll need a few products and tools. Here’s what I recommend:
1. **Buffer/Polisher:** Invest in a high-quality buffer or polisher. Look for a variable speed model, as it allows you to adjust the speed according to your needs. A dual-action polisher is a good choice for beginners, as it’s less likely to cause swirl marks. Like Shurhold Dual Action Polisher – 3100 or SHURHOLD PRO ROTARY POLISHER – 3400
2. **Compound:** You’ll need a marine-grade compound to remove the scratches. 3M Marine Compound or Meguiar’s Mirror Glaze #49 Heavy Duty Oxidation Remover are excellent choices. These compounds are formulated to work effectively on boat surfaces.
3. **Polishing Pad:** Get a foam or microfiber polishing pad that’s compatible with your buffer. Make sure it’s the appropriate size for your machine.
4. **Wax:** After removing the scratches, it’s essential to protect your boat with a good marine wax. 3M Marine Ultra Performance Paste Wax or Meguiar’s M6332 Flagship Premium Marine Wax are popular options. These waxes offer UV protection and durability.
Here’s a step-by-step guide to removing scratches and waxing your boat:
**Step 1: Preparation**
– Start by cleaning your boat thoroughly to remove dirt, salt, and other contaminants. Use a marine-specific boat soap and a soft sponge or brush.
– Rinse the boat with fresh water and allow it to dry completely.
**Step 2: Compound**
– Apply a small amount of the marine compound onto the polishing pad.
– Spread the compound evenly on the scratched areas of the hull.
– Set your buffer to a low speed and work the compound in small sections, moving the buffer in overlapping passes.
– Apply gentle, even pressure, and keep the buffer moving to avoid heat buildup.
– Continue buffing until the scratches are removed or significantly diminished. This may take some time, depending on the depth of the scratches.
**Step 3: Clean**
– After using the compound, wipe down the boat with a clean microfiber cloth to remove any residue.
**Step 4: Wax**
– Apply the marine wax to a clean, dry polishing pad.
– Spread the wax evenly on the hull in small sections.
– Buff the wax with your buffer at a low to medium speed until it hazes over.
– Use a clean microfiber cloth to wipe off the haze and reveal the glossy finish.
**Step 5: Final Touches**
– Inspect the boat for any remaining imperfections and touch up as needed.
– Clean and store your polishing pads and buffer properly for future use.
Remember to follow the manufacturer’s instructions on the products you choose, and take your time to ensure a smooth, scratch-free finish. Regular maintenance and waxing will help protect your boat and keep it looking pristine.
Best,
