Has anyone ever tried to smooth rhino line their keel?

I know the rough finish would not be good. What about the smooth? If you were able to seal it off good would it be effective?

I don't know how thick that stuff is, but it might cause some clearance problems in the pivot area. I would contact the mfg and see if it rated to be submerged constantly. Just my thoughts.

macropoxy 646 is what i used on the bottom side of my boat and by what i read online supposed to be for coating potable water tank intereors. super thick super tough. i bought it as seconds because it was mistinted. Mine came out with more texture than the topside paint because i rolled it on versus spraying the topside, smoother than bedliner and a satin level of gloss. http://cgi.ebay.com/Sherwin-Williams-Macropoxy-646-PW-1-2-Gal-Kit-/330565196848#vi-content

There's a lot of javascript but I don't see any virus trying to install.... using Firefox 3.6

The problem is you are putting a rubber over fiberglass, and it doesn't breathe, so it will (IMHO) start to de-laminate teh hull.

besides how do you clean it and recoat it? big mess in a few years.... will hurt the value of the baot.

cleans easily on my boat and i plan on recoating with the same when the time comes but i doubt it will need it for years if ever because i have no need for anti fouling. as for "not breathing" that is the same attribute that makes expoxy barrier coat keep hulls from blistering.

Ok, good luck!

Would you check back in a few years to give me an update?

What I know is when I put a rubbermaid shower mat on my fiberglass boat, I got blisters (raised bubbles actually) under it in about a months time.

I hope you have better luck!

(if it worked very well, I would think more would use it, and I'd see it in Practical sailor, and on some of the other web msg boards).

well being that blisters are a product osmosis you applying downward pressure via standing on the bath mat and not actually sealing as the epoxy based paint that i mentioned to the original poster as an option for his use. This downward pressure may accelerate the process. If an epoxy barrier coat is applied it prevents blisters because it stops the osmotic pressure from being applied directly to a porus surface i.e gelcoat. You should watch your tone fill bill when all you know of is a bath mat. THIS IS AN INDUSTRIAL FORMULATED EPOXY PAINT FOR CONSTANT SUBMERSION IN WATER TANKS. A VIABLE ALTERNATIVE TO EXSPENSIVE MARINE BARRIER COATS AND RINO LINER. and worth note depending on the year of boat the keel maybe all steel in which case the blistering is a non issue.

Ok, I just sent the company's tech a question on warranty use on a boat hull, and will report back.

Why don't I see it more often if it works well? anyone seen this on a hull?

lets try to get an answer from Macgregor on use on their hull.

and I will post on sailnet and SA to see what others say. If I'm wrong I'll admit it.

it sure would be cheaper and easier than epoxy... .

I did not find any direct answers, some issue on bonding, most use it on the deck, on a power boat issues seem to be lifting off, and some color fading. and weight...

So, I did not find any definitive 'yes its great' threads, some were ok, and some were not recommended.

maybe you'll have better luck finding a actual success story.

personally, I would not put it on my hull... But what do I know!

if you find some success stories, pls post them!

-YMMV.

Ladies and gentlemen,

I have meant no harm in my simple question, which has been lost from sight.

The original question was applying rhino lining to a CAST IRON KEEL.

I see this has has struck a cord, so to continue all fighters must carry shields of steel and swords made from macaroni noodles.

Thanks for the help and trust me, I'll have plenty more questions!

All, have a pleasant day :)

well i tried to stay on topic lol. rino liner isn't formulated for submersion, but the macropoxy is and is as tough in abraision/impact resistance. i did a test swatch on a piece of scrap fiber glass and smacked it with a rubber mallet i had laying around to close paint cans. this stuff is tough and made to be submerged. the reason i used it was so i could beach the boat and so it wouldn't wear off on the bunk carpet while trailering. it is a viable alternative to rino liner, cheaper and made to be submerged.

Not sure if bottom growth is a problem for your situation or not, but I'd stay with a proven paint, something like Sea Hawks...

http://www.bottompaintstore.com/tuff-stuff-highbuild-epoxy-primer-by-sea-hawk-paints-p-9473.html

...Tuff Stuff. It is epoxy and formulated for what you want to do and can be top coated with a bottom paint if you are also fighting growth. We used it for our boat....

http://purplesagetradingpost.com/sumner/macgregor2/outside-39.html

...and along with Sea Hawks ...

http://www.bottompaintstore.com/cukote-biocide-plus-selfpolishing-bottom-paint-p-9475.html

.... bottom paint and have had good luck so far. We are going to use the same combo on the new boat. Anytime you paint most of the work is in the prep work and not the actual painting time. I'd spend a little extra and make it hopefully a one time job,

I think the question was specifically about applying rhino liner to the keel. I was going to use it for my truck bed, an application for which it is marketed, but after reading about the prep I decided against it. I can only assume that getting it to adhere well to a cast iron keel that is regularly immersed in salt water would require even more preparation.
I paint my keel with a white rustoleum primer. I first wire brush the surface so I remove anything that is loose, including rust. I then apply 2-3 coats.
What I like about it is that it proves a really good visual measure of rust development. Where it remains white, no rust. Where it starts to turn pink, rust is stating to penetrate, and Where it turns red it requires attention. I lightly grind that area and apply more paint. I usually do this every other year.
For what it's worth....

It's worth a lot to me, thanks for your input. I think that might be a great idea for my application. I Coated well with united 303. It's a rust barrier/converter used on underground holding tanks and navy ships. I think I'll do like you did and give a good coat of white on top as a tell tell of sorts.

Thanks again.
