Re: how often to wax/clean a boat kept trailered?
An orbital is fine for maintenace waxing, not worth a damn for compound buffing. It depends upon your existing gel coat. An oxydized boat cannot be restored with a flat finish with a typical orbital buffer. You'll need horsepower and sweat to get it flat again. A rotary high speed buffer can be death on stripes, rub rails and such, but with a little practice/patience and liberal use of compound, it shouldn't burn. Gel coat that has been oxydized prior is hardest to maintain, once the finish fails, it's harder to bring it back. Thus, regular waxing is a must to keep the grime from getting in there in the first place. An annual heavy buff will keep things flat, regular waxing will provide the sacrificial layer to protect the gel from the elements. The point is, do everything to prevent losing the top finish of the gel coat. That means weather protection and maintaining a waxed protected surface. Life will be easier down the road for a few well spent hours with a fresh coat of wax.
