Im gonna be doing some fiberglass work on a boat in the next week or so and I have to gelcoat the areas that im doing the work. After im all done with it, the guy wants me to clean it up real good for him to remove some hard water spots. So im looking for a little help with that part of it. Im not 100% sure of the specs on it but it looks like an Eliminator at least 30'. He wants me to do the sides and top of it. Ive done plenty of cars and stuff but never a boat, I have a pc and can get a rotary. Ive got access to pretty much all meguiars products out there. What steps would you take just to clean the thing up, im not trying to remove swirls and all that, just hard water spots and get it shiny as hell. also how much would you charge to do a boat like this?
