Many boats that are made of fiberglass have a coat of paint on them. Generally speaking the more expensive the boat, the more pure colored fiberglass you will see. Why am I mentioning this? Because the heavy duty oxidation remover in this kit is designed for rock hard fiberglass, and not for paint. It is a bit aggressive for paint unless it is super oxidized, and needs a layer removed. This level of scrub is not designed to give you polish or gloss, but rather to remove the surface oxidation. So that is why they provide three different formulas. This kit includes: Meguiar's heavy duty oxidation remover (M4916), boat/RV polish (M4516) and gloss enhancer, boat/RV pure wax (M5616), soft foam applicator pads - 3PK (X3070), microfiber towels - 3PK (X2020), mirror glaze apron.The polisher is to be used as a second step, and finally use the wax to preserve your work underneath. I had a high end body shop for 20 years, and when I was younger I did a lot of hand rubbing in the driveway. It is a lot of work. Full blown professional polishers are for people who know how to run them. Why do I say that? Because it is necessary to learn how to let the spinning wheel scoot off the edge of a plane, rather than doing the opposite and having the wheel dig into an edge, or should I say catch an edge and burn through it. On a car if you are not careful you could destroy an antennae, or a rear view mirror. I mention buffers because they do a lot more work, a lot faster. Also using lamb&#8217;s wool tie on bonnets, on top of the cutting bonnet gives you mirror like results.There are gentler use buffers out there designed for polishing. The PORTER-CABLE 7424XP 6-Inch Variable-Speed Polisher is the number one seller here at Amazon and is tamer than the Makita 9227CX3 7-Inch Hook and Loop Electronic Polisher-Sander with Polishing Kit which is more than twice the power of the Porter Cable. It also takes full sized standard in the industry buffing pads/wheels. If you really want to tread lightly while experiencing less elbow grease you can opt for the WEN 10PMC 10-Inch Waxer/Polisher in Case with Extra Bonnets. The WEN is actually one tenth of the power of the Makita and one fifth the power of the Porter Cable.So anyhow the points I want to make are these. This kit is for fiberglass, not paint, and a lot of boats have a top coat of paint. Hand rubbing is an enormous chore, and if you have a larger boat, at the least you should invest in the Wen mentioned above, or better yet the Porter Cable while exercising some caution. Only if you have a deep desire to master a polisher over time, or are already an accomplished polisher do you need to think about the Makita. I could write a book on polishing techniques, and if you use the Makita on your car, with just one wrong angle on an edge you can burn the finish right down to the primer.Do you have to have a polisher? No because hand rubbing will do a nice job. Polishers have the capability of giving you higher gloss, and deeper depth of fresh glass for better colors. Some people fine paper older glass using wet or dry paper like 1,000 grit, and then use compounds to remove the fine scratches. My philosophy is don't go deeper than you need to.Hand rubbing with this kit will give you very nice results on fiberglass. Save yourself a lot of work, and at least get the Wen. I recommend the Porter Cable for those who are willing to practice and get good at an entry level buffer. By the way do not use this kit, or any polish in the direct sunlight which can take polish residue and bake it into a hard line in no time that is a pain to remove.Meguiar's has been one of my favorites for over 30 years. Highly recommended.
