Paint Job

Here's a link to a thread that covers a wet sand and buff:

The tread is one of many great ones that cover almost anything you want to know about our CC's. You can find them in the FAQ thread that's a sticky in the maintenance section of the forums. If you get a chance, take a look. Here's the FAQ's.

How bad is your boat? What year is it? 

Also just remember, its not supposed to be bright white like today's boats, its ivory. 

though some have a grey base, much less common.

So he used it for a total of 2 weeks when the ice was out?  Sounds more like your neighbor either - can't drive or just doesn't take care of anything . Shamrock just spent 7 years in south Florida and sat in a carport through hurricane Irma. Not a scratch in it's Imron. It's all how you take care of them - can't buff dock rash out of the Dumphy can you?

As to the original poster - it will be cheaper and most likely faster and easier to buff yours out, you are probably talking 2k easily in supplies alone to Imron yours and the fact Imron cannot be submerged for any length of time. My Shamrock has bottom paint,you wouldn't want that on your boat. I always like to use these two pictures to show what can be done with sanding and polishing. It's not perfect by any means,gel defects cannot be over come but from 20 feet looks great.

Gary's Mustang he uses as an example is an extreme case but does show what can be done with the wet sand and buff. 

Also, would you believe that the condition of the Mustang in the picture above was from being in the water for only 2 days! He lives on the Fox river down stream of the Fox Chain of lakes in Illinois.
