2nd time around.. Repainting Glu-Vit..

[RichBKK]

Hi Everyone.. It's been some time since my last post.. I have several questions concerning my prior paint work on the exterior of my boat.. Here goes..

I gave the exterior bottom of my boat 2 coats of Glu-Vit this past Dec.. Great stuff, really doing it's job.. No issues with it.. It's really very well adhered to the aluminum..

After it cured, I light sanded it and wiped it down with actone.. Then painted 2 coats of Behr oil based epoxy paint (thinned with Penetrol).. Came out great.. Was very pleased with it until 2 weeks ago..

The boat lives on a trailer but has been left in the water (dockside, saltwater) for 7 to 10 days at a time thru out the summer.. The paint below the water line is now coming off in huge chunks and sheets.. No issues with the paint on the gunnels or anywhere else..

So, living here in southwest Florida I want to paint with a growth inhibiting paint as I plan on leaving it in the water more this fall and winter..

Questions:

What do I need to do now to prep the cured Glu-Vit for painting it with a growth-inhibiting paint..?? Obviously I'll flip the boat and sand the oil-based paint off----but, then what needs to be done to get the new inhibiting paint to stick to the Glu-Vit..??

Perhaps it depends on what paint I choose to use (I guess..??) and if it requires a primer (to cover the Glu-Vit) before 2 or 3 coats..??

Thanks again for all suggestions and guidance..

Richard

Sounds like you already know the answer to your questions ^^^ Be sure to confirm the paint is aluminum hull safe, some copper paint are reactive w/ the aluminum...

Stripping the paint off? Be careful, some strippers will attack the GluVit too.

Sanding the paint off, should get the GluVit roughed & scuffed too, and be sufficient to give the paint or primer enough tooth to bind to the GluVit.

You also need to decide ablative or non-ablative. I've read good things about ZO paint from epaint.com and using the non-ablative (ZO-HP) as a primer, 2 coats, then 3 coats ablative (ZO)..........

Some experience problems w/ ablative paint not working as well as it should, but typically only when leaving the boat slipped & UNUSED for more then a week. The ablative process needs the water's movement against the hull (or vice versa) to be most effective.

Re: 2nd time around.. Repainting Glu-Vit..

Thank you for your reply and recommendations.. Another big question, here goes:

After making the prior post, I surfed the internet and came across a product called "Wearlon" (Wearlon : Wearlon Anti-Graffiti, Wearlon Non-Stick, Wearlon Foul-Release, Wearlon Mold Release, Wearlon Marine & Wearlon Friction Reducing Coatings. Wearlon is a waterbased, environmentally friendly, low VOC, abrasion resistant, corrosion resistant, ).. They have some very intreting Marine products that have caught my eye.. Perhaps an alternative to appling anti-fouling bottom paint..(??)

Has anyone ever used this product..?? Any pro's or con's concerning it that I should be aware of.??

Thanks everyone..
