Yeah, you need the primer, not much sticks to acrylic or Lexan. That was one of the irritating things about using the 295uv was that you had to pay around 40 bucks for a can of primer that you only used a teaspoon of.
I was just wondering the other day, if that purple primer they sell to prime PVC piping before gluing would achieve the same result – I wouldn’t be surprised, and for only a few bucks. I tried gluing a couple pieces of Lexan together with 795 a couple years ago, just to see how it stuck, and it didn’t take much to pull apart. I should try that again with the purple primer.

I did the aft cabin hatch 3 years ago, and no leaks. I had the some primer for the saloon and v-berth hatches, didn't notice it was the wrong stuff until it was too late.

Cleaned it up all over agsin and used primer second time. Still good after 5 years no leaks.

I dug out most of the sealant around the lens, then took a windshield removal tool to cut the bond between the frame and lens. I used a wire wheel to clean up the remainder of sealant. Wiped the frame with lacquer thinner, put a small bevel on both the top and bottom of the new plexiglass. taped off where I didn't want sealant. Laid a bead of Sika Flex 295uv, positioned lens into frame and pushed down with just enough force to make the lens leves with the frame. I then filled the gap between the frame and plexiglass. You will want to make sure you get as many of the voids as possible. https://www.harborfreight.com/windshield-removing-tool-60298.html Doug.

I only need two things, one is putting a new gasket in and the other is a new piece of Plexiglas. I can buy the gasket and the glue and the local shop can duplicate the glass easy enough. Thankfully I don't have the kind of hatch that opens from the outside, so there are no knob or O rings to leak. Question - how do you get the hatch off? The pins don't look designed to be removed easily. Do you cut them and then get new ones?
