Great video thank you for sharing your professional knowledge. I have a similar four winns but the stains are much worse! Question - some marinas block the boat and remove the trailer before spraying. I assume this is to avoid damaging it, but I would think it allows them to also clean the areas that the bunks hide? Is this a big deal leaving the bunk area? Just trying to decide if I go through the effort removing or just cover the trailer. I have a nice aluminum bunk trailer.

Thanks for sharing your expertise. Do you need to cover the trailer to keep it from getting damaged from the acid?

You have the boat in sea whater for 1 year with out untifouling. What about osmosis?

Question- when the acid get on the ground can this be harmful to dogs or cats? My understanding is you cant do this on your driveway?

Thank you for sharing. I am looking to purchase a boat that needs this process badly. What do you put on the hull after doing the acid wash? Polish and wax?

[MARKLOCKWOOD]

waxing helps a good high end marine wax plus get the exterior and interior with uv protection and upholstery cleaner for leather conditioner as much as they cost why is not doing all they can keeping factory fresh then down the road re-sale is higher. outdrives use oem paint.

Muriatic acid will work just as well, available at Home Depot

if I use the toilet bowl cleaner, isn´t there any problem with the boat decals?

[pipakkos]

Is it possible to use straight a hydrochloride acid on the boat?

do you use it all the way up to the rail?
