Just thought I'd post an update. I have compounded and waxed the hull with presta gel coat & ultra cutting cream. Followed by 2 coats of fleet wax. The results are nothing short of spectacular on my 23 year old Freedom. Perhaps he was just hamming me up, but the yard manager said I could retire from my day job & he'd hire me to poilish boats.
I've wet sanded the topsides as they showed the most oxidation, much improved, but haven't compounded & waxed yet (waiting for my 3" polisher to show up from griots).
On the topsides I have many black specs that don't seem to sand out, not sure what it is, embedded dirt or mildew? Most of the specs were removed with the wet sanding (400-800 grit), but some remain. I figure I'll compound and seal with wax and hope the sun bleaches them out?
A point of information, the Presta Chroma 1500 doesnt' seem to exist any more. Ultra Polish is thier new "heavy polish" followed by the swirl remover as "medium" and finally hand glaze as lightest. I've got the ultra polish & swirl remover on order, plan to experiment on the topsides this year and then the hull next season...
Regarding upkeep - it didn't take but one rain event for the black water streaks to re-appear (even over the wax), any recommendations on how to treat them, Boat soap alone doesn't seem to do it. Starbrite makes a "black streak remover" Star brite - Catalog - Product Detail
. Or perhaps a "cleaner wax" (one with some mild abrasive in it).
Lastly, I'd like to request a similar tutorial on filling scratches in the gelcoat. All the dock rash from the previous owners is now on proud display since the rest of the hull is nice and shiny... Probably next fall's project
