I just purchased tri-lux anti-fouling paint for the outboard of my 220 sundancer. Do I need to primer before painting. I am planning on putting this over the current paint. The guy at the marine store said no--but I want your opinion also.

Thanks---Marckmann
 
TriLux is an Interlux product. They are one of the biggest and best makers of antifouling products available to us. What the paint salesman or other boaters say isn't nearly as important as following the instructions Interlux provides for use of their products. Read the can label, go to their website and if you still have questions, they have about the best technical services folks in the business .......their toll free # is 800-468-7589.

You are correct to ask questions and to determine the right application methods. Bottom paint can be a funny creature. Sometimes what was used previously that you overcoat or even the amount of time between coats or layers can mean a the difference between a successful job and an awful mess.
 
My .02 worth... Brush-on is MUCH better than the spray-on.

Primer? Yes, as per the instructions on the can.

Cover the anodes or just do what I do, paint over anodes that need replacement then replace the anodes. Cover the stainless rams of the power trim. Tape off the boat. Leave a 1” or more gap between the drive paint and the bottom paint.

Question, why are you using it at all? I hope it’s not for anti-fouling. With the fresh water of the Midwest it’s simply not needed. Actually, compared to cleaning 1x/year versus painting it 1/x year it’s more work to paint then to clean.

Now if you have an issue with zebra mussels, then no problem, spray, brush or roll away.

You need to get down low, under there, in there, around there. It’s just easier to get there with spray. If you are adding this to prevent zebra mussels from sticking to the outdive the most important part to spray is the very places you would have a hard time getting to with a brush or roller. The bottom skeg does not even need it. It will wear off from the skeg in a short time anyways. The bell housing and all unexposed areas need it. Just spray it on the rubber bellows. It will come off but there is do harm done.

you can use primer but it is not very important step

best way is to wash lower unit, scuff it with medium grid sand paper (220 or 320), wipe it with paint solvent, acetone or something similar and paint using paint brush
remember not to paint zincs, put to much paint over water pick-up holes etc
 
that paint is very expensive to be painting the whole bottom with it.

local MM dealer uses the absolute cheapest anti fouling money can buy and no one has problems.
