hull buff
For the last few years after using lots of products, I have had good results with meguiars, west marine, has a 3 part kit, first step is color restorer , or oxidation remover, and is a must, do not even try to do anything with out doing this first, then there is a polish and finally a way, i do have a 7 inch polisher, but truthfully have better results using , clean terry towels, , the trick seems to me to be the clean surface of the towel which u cant have with a buffer unless you have a lot of pads,This has worked on our 89 h23 and we get lots of compliments, usually one time for hull will due it for the season, top usually requires some work during season, ,good luckMike B
