Used Pontoon Trailers

I have a new Avalon pontoon boat that has been in salt water for a month. I took it out recently and found a considerable amount of baricles attached to the pontoons and the motor. What can I use to reduce or avoid this problem. I used a pressure washer to remove as many Barnicle motor and pontoon, but parts of the pontoons can not be reached while on the trailer. Even after powerwashing with water right, there is a roughness to the pontoons. What can be done to remove the cloak of the roughness and pontoons.

+ You must first obtain all the barnacles off. If it means jacking the pontoon trailer of a section at a time, then that is what you have to do. Be very careful, and blocks of safety at Dun and age, where you can while there is no danger of the drop on you or trapped. Then you must clean the boat as smooth as you can get. The smooth surface the better. I've seen people use good quality wax paste to make it smooth and I seem sailboat racers use a layer of soap to smooth the bottom and prevent barnacles, but they are very temporary solutions such as Barnacles are ubiquitous. The longest lasting solution is the use of a painting of seabed good for at least two layers. Even that will not last an entire season. Interlux and Petit are the ones I tried so far.
Good Luck, Safety, and
Happy Holidays

Once you get it clean and ready to apply the primer, make sure the primer is for aluminum hulls. Normal primer will accelerate corrosion of the hull.

Here is a site of marine paints:

Antifouling bottom is necessary to ensure that it is aluminum. If left for a time in hot weather it will get some anyway.We (in the Chesapeake Bay, brackish water) have the worst problem on the tree and the proposal, the metal, then maybe they prefer. When the boat is out of the water power washing.

The glue left by barnacles come off a fine (180 or higher) sandpaper wet and dry.

ridenicely has a point that I want to emphasize:
the only thing that keeps barnacles to a boat bottom paint anti-fouling.
Period.

almost all anti fouling bottom paint is made of copper.

copper-based paint in the salt water goes through electrolysis, to eat the aluminum hull of your boat in a few weeks. No kidding. considerable damage in a short time

You must either use an anti fouling specially designed for aluminum, or

the use of many many many layers of primer and first barrier.

The painting is a system. A painting is to go specific with specific primers.
Read the boxes!

get clean ... clean. then find a quality anti-fouling "paint. Even then, you will always get some, but not covered in them.

I just saw this question on a forum pontoon. Maybe it was you. If not, go to www.pontoon.net and go to the forums. Then either search or go to the General Forum. It should be on the first or second page of discussions. BTW, it is great forum. Good luck!
