Does everyone paint the bottom of their boat every year? I am in Lake Erie....and no matter how I prepare the bottom there is always a little slime when it comes out in the fall. What is the opinion will there be more or same slime in the fall if I don't paint the bottom? Can I just touch up some areas??

Brian,
I don't paint every year but I have a slowish trawler. I too am tired of the slime issue
and even using expensive Awlgrip ablative paint it doesn't stop it. I am in Lake St. Clair
north of you.
I sure would like a suggestion from somone with good experiences using an ablative that takes
care of the slime also.

Craig I also use ablative paint. When first got the boat used hard type paint...then figured out real quickly why have the build up of paint over the years. Craig our issues are small compared to the people who are in the ocean with all the things that grow on their boats. They are probably saying a little slime so what!! Need reply from fresh water people.

We are at Toledo Beach on Lake Erie...
Also looking for input on what's best to apply.
Standard Interlux or more expensive Ablative type.
I have had it painted annually for 4 years. I have Std Interlux now and am not happy about the paint flaking off at the water line (and some other areas).
Any advice is appreciated! It's that time again...

1st - Interlux and pettit have come up with additives to combat the slime build up. Irgarol was introduced a year or so ago. It doesn't kill all the slime, especially in TBM, but it does help. As for painting the bottom, if you don't expect a lot more build up in the fall when you pull it. And, over time expect that you will have blistering problems as the growth on the bottom has to anchor somehow, usually by penetrating the gelcoat. Ablatives are nice if you just sit, or move very slowly. If you use your boat and/or travel above 15 knots consider VC-17. It is self polishing, has irgarol, and a teflon base which cleans itself as you motor.
As for the flaking, SAND more. Gelcoat, when healthy, is very hard and very smooth. If paint is flaking off, it is because it isn't holding on to anything. Any other questions contact me through http://www.mikesmarine.com

My experience: When my boat was 1 yr old, I decided to keep it in a wet slip and so I had the bottom prepared and a barrier coat applied, then 2 coats of whatever Interlux' best ablative paint available in 1992. It lasted 7 yrs with the boat in the fresh/brackish water of the delta.
I pulled the boat 3 times each summer to high pressure wash the bottom, transom and outdrive. Also, I discovered that by running my boat into salt water for about an hour on plane, the bottom got really clean.
Brian, I'd suggest you run the boat into salt water if possible, then haul and power wash it while it is still wet before putting it away for the winter. You might be able to go longer between painting that way. Also keeping the boat on an air dock during the summer might turn out to be cheaper then doing the bottom paint thing every year........in the winter you can deflate, clean and store the air dock.
Good luck!
Then I got myself the air dock and have never bothered to repaint the bottom

After lengthy conversations with Interlux via phone and e-mails (their tech department was most helpful), I have learned that their latest-greatest "flagship" bottom paint (Micron 66) is a true self-polishing copolymer. One can sit dead in the water and never move for the life of the product and it will give the same protection as if you were underway regularly. This is a wonderful feature for those staying in the water year round in areas where it is otherwise too cold to operate during the off months. There is one major provision though, and that is the following: To use this product the salinity has to be above .75%, otherwise it is ineffective. In essence, don't use it unless you moor and operate in moderately brackish water or saltier.
V1rowT8, I use the Micron 66,for our boat is docked in a brackish creek 2 miles from the salty river I have it painted every 2 years but also have a diver clean the running gear once a month from March to November. Suggest you use apply 3 coats as reccomened. Did the Dealer also reccomend painting or treating the running gear? if so with what products.
I posted this in this forum in a dirrerent topic
I too am ready to sign on the dotted line for a new express cruiser. After a bunch of online investigation I found what seems to be a better for the money product in the Blue Water line of marine paints. I am going to use their 2 part barrier coat product. They suggest 4-5 coats primer to build a 10 mil thickness. I am then going to paint with their 45% copper ablative product in red. I'm going to finish with their Copper Pro scx67 in black. It is 67% copper, & was rated "excellent" & a "best buy" in the March 2005 Practical Sailor comparison of 54 different paints. Many have suggested to paint it a different color for the base coat because then you will know where & how much of your outer coat has worn. These products are copolymer which means that the molecules of paint & poison have been combined to wear like a bar of soap. I Boat in the great lakes (Michigan, Lake St Clair) where the water can get to tropical conditions, so growth can get out of control. I found the best prices at eboatworks.com
It just makes me want to cringe when I think about putting a piece of sandpaper on a brand new shiney gelcoat hull!!! Good luck with painting your new boat.
