The best pads for the polishers are one piece...they thread right on to the standard 5/8" shaft of the polisher (which all serious polishers share)...they don't have strap on bonnets or rubber backing pads...they are about $18.00-$20.00

Here is what the manufactures rep for "Buff Magic" wrote me...

Our Buff Magic is used extensively by many boat manufacturers for polishing sanded gelcoat for repairs during the production process. All gelcoat sprayed after the fact of being pulled from the mold is sanded, and orange peel is unavoidable, so if yours is slight, you are to be commended on your application skills. Buffing from 400 is not recommended, nor is it a common grit to start buffing from. Most manufacturers buff at a minimum of P600 or finer. And for large areas such as an entire hull, you will highly benefit from going finer, such as P800 or P1000. The time and effort in sanding to a finer grit will save buffing time tenfold compared to the extra time sanding. Using only 400 grit will leave too coarse of scratches requiring much more buffing time and effort, and also will require multiple applications to remove all of the scratches. Multiple applications in addition to being time consuming will degrade the gelcoat beyond what is necessary, and also generates a lot more "heat" which can shrink the gelcoat, and create irregularities, and can cause a "print through effect" of the fiberglass behind the gelcoat. Additionally it is much easier to produce gloss when buffing finer scratches such as P800 or P1000. Buff Magic will work effectively from P600 and finer, but for your application to large areas, P800 or P1000 is recommended.
