My .02:

Alarie has the right idea.

My 23' hull was in good shape but VERY faded ( white color )! So, I sanded the entire hull w/ an electric D/A with 600 grit paper. Then w/ 800 grit paper until it was as smooth as a 'baby's bottom'. Then, I compounded the hull 2X w/ a very good commercial wheel, and a 3M compound - putting some muscle on the wheel. Then compounded w/ 3M " Finesse-It " for the a very fine polish. I was blown away by the results ! Looks brand new !

And, I am a total amateur taking advice from pro's.

However, I did not have any cosmetic work to do here. If I had minimal work, I would repair, gelcoat, blend and do what I did. If it is more than a little, I would do exactly what Alarie said - I actually like the idea of spraying w/ a dye to see that you get all the sanding marks out. GREAT idea - next time... Oooh, did I say next time - someone slap me !!!
