3M Finesse-It II, and Surhold Buff-Magic: have you used both?

[Rich]

Is there anyone here that has used BOTH of these products?

I've had good luck with the 3M Finesse-It II, but I hear good things about the Yacht Brite (now Sur-hold) Buff-Magic.

So I'd like to hear from anyone that has used both products for polishing the fiberglass on a boat.

I've seen many posts that just say "this works great, it's the only thing I would use!" but most of these posts online are from someone that only has used one product or the other.

I'd like to understand how the two products differ, what is different and why? Are the results that much different from one or the other? Is there more or less effort for the same results?

I have a fairly large boat to polish and wax (38 ft) so I'm open to new ideas and procedures. I know the Finesse-It II works, but I'd like to consider the Buff-Magic if it has any real benefits.

Both of these are not inexpensive so I'd prefer not to buy enough do to my whole boat, and then not like it.

Thanks for sharing your experience!
