I saw your post this past Sunday. After doing some research I decided to buy the 8oz "kit' for my 340 Sundancer. I figured "lets try it on a small area before I commit." After receiving it, I was a bit skeptical (things like don't apply in direct sunlight, apply when the temp is between 60-80 degrees, etc., which is impossible to do on a boat that's in a slip in FL...it was 100 degrees today!)
I called the company today. I think I was talking with the owner. It seems like he really knows what he's talking about. I'm going to try it on a small section, while continuing to compound and buff the rest of the boat.
I'll let you know how things go.
