TotalBoatAluminum Boat Barrier Coat (Quart, Gray) 32 Fl Oz (Pack of 1)

1000% reccomend this. I bought this as a precaution to help stop any leaks that nay or may not happen. It popped up when I google waterproof barrier undercoat for a boat. This product is not rated to be waterproof I later found out but once I applied it I felt super happy it went on perfectly to my aluminum 16foot boat. I do reccomend getting a top coat for once it drys. Use inside as well if you can

What a great product, just a few things that helped me... It is going to be too thick out of the can. drill mixing attachment to mix the base and hardner together. Thin 10% with totalboat 200 thinner and roll it on with a bunch of small foam rollers. Wear a good respirator, probably too dangerous to spray without a full force fed suit as I have read these epoxies in aerosol can damage your lungs real bad, not worth the risk.. It etches and bonds to even lightly oxidized aluminum. I quit sanding and just washed clean and applied, seems to be holding up no differently than a lot of sanding...

Worked great, would recommend drill with mixing attachment. And wear gloves.

The media could not be loaded. 5 step process, lot's of labor, #1. sand boat, #2. JB Weld (Marine Grade) any pock holes, #3. Sand boat again, then use the recommended etching spray, #4. apply 2 part barrier paint 3:1 mix rolls on thick not like paint 3 coats minimum are recommended, last step #5. apply Aluminum AF paint... Well worth the end result with maximum protection, 3 quarts yields 3 coat's on a 14' boat...expect about 2 days to apply with day time temperatures being considered, read all instructions carefully, very detailed wear appropriate clothing and read entire procedures... Very impressive 👍😎

Used to prime and protect a boat project. It goes on very thick and rough even when thinned out. Reminded me of bedliner. But that could of been the application process. Cheap airless gun.It did cover well and did a total of 4 coats.

I only put it on the bottom 8” of my boats, the grey paint above it is PPG auto paint. It is thick and that’s what you want. I use a drill and mixing attachment to blend the base then add the hardener. I fish and gig flounder in shallow oyster filled bays from Galveston to Brownsville Texas. The bottom of my boats are always running on oyster reefs!If someone says it came off they didn’t acid etch and use conditioner on the bare aluminum.Some May say it’s hard to apply because it’s so thick. Once you get it mixed right it’s is easy to roll on. I would not try to spray it but you may be able to if you get the can hot in the south Texas sun and use an airless. The stuff does what it is supposed to and filled small pin holes from salt water corrosion. I did all three of my Jon boats with it... fishing, floundering and duck boats!

Easy to use I put this on my 14 ' 1969 sears game fisher boat I put it on over gluvet prep work before I put on both I used a wire wheel and cleaned around all rivets Appling the barrier coat was easy used 4" foam roller did one coat I also applied it in the inside as well one can on the bottom and one can in the inside very happy with it..

We have a 15' stock tank pool that our kids "swim" in during the summer. I keep chlorine in it, so last year it began to rust. I tried sanding the rust down and using flex seal, and that flaked off almost immediately. So this year we, again, buffed out all the rust and used this, and it is working incredibly well so far!! It covered the bottom of the 15' pool thinly and about 6" up the pool wall. I would like to put on another coat this fall for extra protection, as the can calls for multiple coats. But this was a great solution to our problem!!
