If you had used a rotary buffer, not a RA and a good rubbing compound like Total Buff , 1,000 grit would not only have worked but would probably not be needed. a light 600, maybe 800 and then buffing.Have almost finished my 228. The hull I compounded using 7” and 3” dual action polishers. I used Gyeon Q2R Marine Polish Step 1 followed by Gyeon Q2R Marine Polish Step 2. If I did it again I would just use Step 1 the improvement with Step 2 was minimal with a light coloured hull. I wet sanded the gunnels, cabin etc. that were more badly oxidised. Oxidation will polish but not as well “fresh” gelcoat And you will get back the original Grady colour with wet sanding. I started with 800, then 1200, then 2000. Make sure you remove all sanding scratches left by the 800 grit with the 1200 or you will end up with a nice glossy gel coat but in the right light you see all these fine scratches. 2000 grit probably not needed as a heavy cut compound should remove scratches from 1200 grit. The gelcoat looks like new.
Hull stripes to go on then a ceramic coat.
I had the same concerns. Was going to try one of those longer rectangular hand pads from Chemical Guys. Are you using the circular ones?I have a 7" Dewalt polisher that works good for the large exterior sections but for the interior liner I would be curious to know what is a good choice for small areas. The big 7" is not good for those tight areas and my hands start cramping after awhile. What's your favorite?
Long story that is really not finished yet Glacier.Confused. Was the regular price $2k, and he gave you a discount for something else? I would pull my boat to SC for that job for $1K.
