Buffing the Hull - Random Orbital Buffer?

I purchased my 1996 Hunter 336 in 2004. The boat had been on the hard for a season and had some minor oxidation on the hull. A little one step wax from West did the job and she looked great however my arm nearly fell off in the process.

Looking for thoughts on using an Random Orbital Buffer to clean her up this off season. Any recommendations on brand of buffers or cleaners for the hull? She has built up a decent amount of "chalking" and oxidation over the past two seasons.

Thanks!

Matt

Buffing the Hull - Random Orbital Buffer?

Try an auto shop - I use a Turtle Wax orbital that has worked out real well - easy to hold and very smooth operating. I recommend all the Maguire cleaner/polisher/wax products - they may be cheaper at the auto store than the boat store...

I''m surprised you have much oxidation on such a new boat. I guess I''ll bite my tongue regarding my opnion of Hunters. Hopefully uyou should only need to use wax on it...

Buffing the Hull - Random Orbital Buffer?

It is nearly impossible to get good results using a cheap buffer. I tried numerous under $100.00 buffers and until I got the Makita I have now never got the results I wanted. I discovered that you need a buffer with a slow "no load" speed and good 3M buffing pads. Pads come in different "weights" usually the whiter the wool the more abrasive the pad. Use a more aggressive pad for oxidation and then when you "polish" move to a "fine" weight pad. I actually got so frustrated with my results that I paid the local body shop bufing guru to teach me the fine art. I paid them an hours labor and he shared all the tricks with me it was well worth it! This is where I leanred about pad weights, compound buff wax and the fact that there are no shortcuts!

Buffing a hull is always at least a three step process if it''s oxidized. First compound with the lightest compound that will remove the oxidation. Second polish the hull with something even finer than 3M Finesse It. I like McGuires #9 Swirl Remover for the polishing step. The third step does not require the buffer and it''s the wax stage. To get the best, longest lasting results use a carnuba paste wax like Colinite Fleet Wax or 3M''s carnuba paste wax. Here''s a link to a great buffer. The feature I like best is that you can control the speed with the thumb wheel. Just copy and paste the link into your address bar..

Good advise from Acoustic. I like the 3M products. Finesse It is a great polish.

One more point, with Heavy Oxidation you may want to consider going to a wet sanding process. Usually reserved for older boats say of the seventies vintage. With my old boat, I found that I was working very hard to get the results I wanted using rubbing compound. I went to wet sanding and found the results were superior with less effort.

Many thanks.

I may be incorrect in my use of "oxidation". There is a very chalky film on the hull. I was down yesterday and and used a one-step wax/cleaner that cleaned it right up on the small section I tried.

I will likely use this with either the makita or porter cable buffer and then go with a second wax as recommended for longer term protection.

Thanks again!
