I have a painted Aluminum G3 bassboat that I absolutely love. However I do have one problem that is not related to the actual boat.

I moor the boat in the water all during the fishing season and it accumulates quite a nasty scumline and crud from the waterline down.

Waxing the hull prior to launching helped the first couple years but now only elbow grease or dragging it to a pressure car wash will remove the crud. Anyone else have this problem and any possible solutions/remedies? Spray on, hose off cleaner? Have tried a few but to no avail. Any help would be appreciated.

Try using some of the aluminum wheel cleaner for the wheels on your car.  Not sure what it will do to the paint so you may want to try it in a small area before you do the boat, but I use it on my fiberglass jet boat and it works great and doesn't seem to hurt the gel coat.  I use the Eagle I in the black bottle and takes the scum right off.  Spray on and rinse off with very little elbow grease except for the really gunked up spots.  Otherwise I have found that extra strength Fantastic works but it takes some rubbing.

Thanks-

I'll give it a shot. I used to have a Bass Tracker unpainted and man the gunk grew on the hull pretty quickly. At least with the painted hull, I got 3 years without growth but have gotten lazy the last few.

I'd recommend going to a reputable marina and asking them what product they like to use. My marina recommended a product called "Slimy Grimy" believe it or not. And the darn stuff works! Takes a bit of elbow grease, but not too bad.

this is what I use on my  v hull, and what we use on our pontoons, that sit all year in the water. I use Simple Green and a light scrub brush. spay it on and scrub the line off. make sure you rinse well. it will also take all the wax off, so you will need to wax again.

Easy and inexpensive: Go to your local supermarket and pick up a couple bottles of Sno-Bol. Apply with a soft brush - let stand for a couple of minutes and rinse. It will clean it up like it is new.

Will it affect the paint in any way?

Sounds great. Thanks.

I have a G3 also, but it's the dull green/camo color. I purchase "Kaboom" from the dollar store and it works great. The only problem might be if you have the gloss paint, which might dull.
