yep those bed liner spray on kinds will always peel off the bottom as they are not made for that type of use for sure.
K5 is sprayed on like your bed liner stuff but the prep is alot more involved and the K5 is 100 times stronger then bed liner
Sounds about like what I need, as I beach my boat on oyster beds a lot, this is pretty rough on a hull, particularly on the center strake. I'm never running in rivers where there are boulders, so, I don't really need to 'rock-proof' my hull....I just need to make it a little more abrasion-proof.
The boat already has a coat of 2-part Rustoleum truck bed liner, for the most part, it's holding up, but there are a few places where it's worn, or peeling.
It might be more trouble than it's worth trying to put another type of coating on there, though, because everything has to be sanded to bare metal to do that, and the existing coating is very tenacious. So, the prep work alone would be a major PITA.
I'm thinking that since the center strake of my hull is what takes the most abuse, it might be better to install one of those keel guards on that strake.
Same thing on my 16' triton. When I hauled it out a few weeks ago to do a little routine maintenance and cleaning, I noted that the first few feet of the center strake was eat up with electrolysis. It hadn't gone all the way through to the point of leaking, so, I used some "Ce-Ram-Grout" (2 part ceramic grout) to fill in the voids, and faired it down smooth. This ceramic grout is what they use to repair rusted out storage tanks, and it's also what marine repair people use to fix damaged metal hulls.
Good thing I caught it in time, otherwise, I would have been welding a piece of aluminum angle to the center strake to repair it. And unless I took the 50 HP motor off the boat, and had a way to flip it over, that would have meant welding it overhead (that's always fun with aluminum...LOL)
Anyhow, once I repaired it with the grout, I took it over to a friend's shop, (since he has a boat lift) along with a gallon of Inter-protect, and a quart of new anti-fouling paint. So, when I get it back, it will be impervious to saltwater, at least until the paint wears off the center strake again.
So, I'm thinking a keel guard is the best option in both cases.
