Re: Bedding Deadlights w/ Butyl tape, DC795 and Screws
I would add one thing. Any holes you drill in the acrylic i would machine/sand in a small radius on both sides to help avoid any cracking once tightened. Leaving sharp edges anywhere can lead to cracking down the road.
I basically 'troweled' the 795 on so that we had full coverage of black 795 under the port light, tightened panel gently to avoid dimples as much as possible, then removed the excess before running the outer bead. Alternately you might consider painting the under-portlight area black first.
I think this may be the best coarse of action. Acrylic can have some movement.
