Default Is this HDPE on a drift boat hull? If so how to repair?

Just got a used drift boat. It's a 91' Fishrite. covering the bottom of the hull is basically a sheet of plastic. I think I may have gotten lucky and it is HDPE. However it is cracked in a couple of spots so I want to repair it instead of replacing it.
Is this HDPE?

If so How to I fix the cracks?

Looks like a heavy coat of gluvit to me.

It looks like a heavy coat of glovit or Coat-it. I wouldn't worry about it. Wait till summer, feather it out and slap some more over it. If it's your first drift boat, you'll have a lot more of those spots by summer. Get out and enjoy your new boat.

It doesn't look like Glu-vit, but it does look like Coat-it to me. I've applied both to the bottoms of driftboats and Coat-it mixes black. That looks black.

The color looks like coat it. The breaks make it look more like Gluv-it. Either way, keep on fishing until the weather warms up. Then flip it over and figure out what it is then repair accordingly.

I'd consider giving that trailer a little TLC while I had the boat off too... Good summer project!

I have Coat It on the bottom of my glass DB. This looks like what's on the bottom of mine. I mixed and applied about 15 years ago. It did turn to the grey color over time and the rock scratches are a lighter grey.

Your photo shows a VERY thick layer and I suspect this has lead to the cracking and delamination problem. As with lots of paints and epoxies "MORE IS NOT BETTER". These coatings flex with the substrate when in thinner layers. The bottom of my boat is aprox 1/16" coating and it does flex. No cracks or delamination problems yet. I believe the aluminum bottoms also flex.

When I get ready to re-coat, I will sand bottom of mine down to glass and re-apply.

Don't have any Idea as to how to repair with the thickness you have and not have the same problem later.

Coat-it comes off very easily by warming bottom with a weedburner torch and scraping it with a 3 or 4 inch puttyknife. I also think that trailer needs a little attention.
