    You know, there is no need to be a sailboat or powerboat-er. You could have both.
    I have never seen a joy stick jet drive in action, I drive a Zeus pod and enjoy the joy stick, but like you I started driving sailboats. I try to use the gears and wheel to maneuver as much if not all the time, I like the idea of joysticks as back up, but they are very good.

    Be sure and let the painter know what you used, and maybe supply the MSDS. The manufacturer lists Polydimethylsiloxane as an ingredient, which is defined as a silicone compound. There can be paint adhesion problems, so it's best to forewarn the applicator so that sufficient steps are taken to prepare the substrate.

    If that's the case, you probably can get away without doing the jet control upgrade.

    d_meister and Cape J, agreed fully on both counts.

    I may be dodging a bullet re the jet control upgrade, or perhaps just being naive about the impending doom of this thing failing sooner than later but-- I can use the boat until it fails and then deal with it.

    So far so good, and thanks for the input and education here.

    Hence my previous comments about unnecessarily adding $$ to the painting costs. I hope he's not hit with some "removal/prep" cost add on, and a refusal to guarantee the work unless its done.

    He has. Silicone causes almost any paint to lift and the prep has to be to a T.

    Given the wide variety of miracle washes, waxes and coatings wouldn't prep with that in mind be a normal part of the painting processes? After all what owner knows everything the previous owner used.

    In short, NO. Dealing with silicone you have to repeat that process several times to ensure there is ZERO silicone left on any surface....so LOTS of rags and lots of solvent and lots of times wiping it.

    You can also wet sand it, and clear it with Awlgrip clear. It lasts for several years until it starts to peel.

    Seems that mean anyone painting a boat after buying it has to wait (how many years) to know whatever the previous owner might have used has worn off. Seems to me more likely it's up to a painter to make sure a hull is properly prepped if they don't want to be repainting at their cost.

    I'm certain the OP had good reason, but my thought is that if you know you're painting in a short while why apply it in the first place? It can only add negatives to the ultimate goal which it seems it has. My own thought is that restorer stuff stuff is, as the OP said, a cheap solution for someone who is not going to invest in a quality paint application.

    Top Coat F11 is "water based", lasts "3-6 months" and "To remove TopCoat® F11®, you can use aliphatic or aromatic solvents (i.e., glycol ethers, benzene, toluene, hexane) or even a high concentrate Isopropyl Alcohol will break it down based on how much TopCoat® has been applied."
    The OP is looking for an easy way to make his hull shine for a couple of months. I can't personally attest to how good or bad it is but per its advertising it fits the bill for what the OP is seeking. With a planned repaint over winter it's the ideal vessel to try the stuff on and I for one will be very interested to learn more about it from a member who has used it rather than from the advertising. If it works it could be bad news for boat waxers. Whatever he puts on will have to be removed in the prep process, but that's why painter prep before painting.
    Hopefully, if the OP tries it, he'll update us on how it was to apply, how it looks after applied, how it looks till he hauls and how good or bad it affects the prep and painting process.

    Thanks NYCAP123 you get an A+ on reading comprehension here,

    To see how it looks after applied scroll up to post #18 and OPEN the picture, its clear where I applied and where I did not. Using a foam applicator pad, and the spray mister the F11 came in, I did the K-mart 36 in about an hour. This is a 2-beer project for most of you guys. It is initially very shiny, but won't hide the scars of evil living and dock engagement or low-quality paint matches in bad repair areas.
    Never before has the term 'lipstick on a pig' been more relevant, as the paint condition is bad, but truly it accomplished the goal for me.
    I now also use it on other boats which have far better quality gelcoat and the result as anticipated is a better outcome.
    I think this is the kinda stuff you see at the boat show, where the cheezy guy wearing polyester pants and a small headset/microphone has a demo table setup next to the fresh popcorn stand where he wipes the stuff on a sample from a dirty boat and voila it looks new, everyone gasps in amazement
    Mission accomplished for me, but not a miracle cream just a really good temporary fix for people in my predicament.
    Yes, any good yacht painter had **** sure better be ready for anything. Of course I"ll mention to him as a courtesy that the goo was put on it, but really any reputable painter is going to DA the whole boat and use plenty of solvent to clean up before shooting the primer. Seems obvious to me.

    DK about my reading comprehension since I missed post #18:oops: but I'll plead busy, lol. I'm impressed, and think I might try it on my vehicles (which are in a lot better shape than that hull. I'd appreciate if you'd post some pics when you haul to see it a couple months later. Also let us know if the painters have and issues. Thanks.
