My Mom recently took delivery of her new Tom Cat, "Knoty Lady". It arrived at the shop in Oakland and sat for about three months while it was kittted out. Plenty of industry, railways and airports to develop a substantial layer of fallout.
Having transported the vessel to the new birth in Santa Cruz I suggested it probably needs a good cleaning and a coat of wax. Mom said she got some "cleaner wax" at West Marine. I shuddered. More often than not "cleaner waxes" are more cleaner than wax.
I have been detailing cars for ~20 years. If there's one thing that makes pro detailers wince is "cleaner wax".
Dad and I immediately got on the web to research gel coat preparations. I found Gel Coat Labs which I later found out to be an arm of a well respected company
http://properautocare.com. I was actually a bit upset to discover the company wasn't actually a "Lab" that studied gel coat.
Being a factory trained Meguiar's guy from 1988 I was happy to see my folks had chosen a Meguiar's product. Still I was uncomfortable with a "one step" cleaner wax product. They had a bottle of Meguiars #M50 Cleaner wax. I squeezed some into my fingers and was suprized by the lack of abrasiveness and reassured by the emollient quality I have come to admire from nearly all Meguiar's products. The 3M stuff is way too "granular" for most non pro, non body shop guys. Their stuff always makes my hands dry. Meguiar's . . . you're soaking in it.
So I get down to the boat with my whole detailing kit, trash bag full of rags, solvent, claybars, tape . . . B&D 6138 rotary buffer with my full pack of Meguiar's Softbuff foam pads.

I try a bit of the #50 on a spot that appears to have some sort of tree/berry stains with a W8000 pad. It's nice and smooth, not abrasive at all. Doesn't really take the berry stain out at all. Well that's good from what I gather having read all the stuff about not being too aggressive with gelcoat. I turned up the rpm's on the buffer and leaned on it a bit more. Nothing. I now knew that this compound was very gentle and it would be very difficult to damage the surface with this combination of pad and compound.
Technique helped me here in not damaging the surface I expect. I figure about 70% of my buffing was done with one hand, only using the weight of the buffer to grind the gelcoat. This is where the consistency of the product comes into play. It must not be too thick. Water it down or use some quick detailer to loosen it up. see below
In hindsight what I probably should have done was get there alot earlier, wash it with Dawn dish soap, claybar it, and then use a solvent like Pre-Kleano or GROW Super Kleen to really get the fallout and stains removed. Then hit it with a nice coat of liquid wax. Then come back the next day and put another coat of wax on it.
But . . . it was a brand new boat, maybe I didn't get all the stains out but it is now protected. From what I gather, gelcoat is quite soft and those stains should come up in a few months with regular attention.
I also wanted to doctor up the #50 with some cornstarch and water to make a more abrasive cut product but I had left my cornstarch at home. I would have taken about 6 oz. of the #50 into a squeeze bottle, added a couple of nickels or stainless steel nuts/washers, 1 T of cornstarch to test and then add more if needed. Add water to make it loose. The nickels/stainless are there to mix it up.
I also found the #50 to load up the pad after awhile so I just sprayed some quick detailer or water on the pad to loosen it up.
I think I need some help with the "cast" tread in the surface. I've seen specific products but don't really understand how to apply and remove these products and what exactly they are supposed to do . . .
Any advice would be greatly appreciated.
