Yup… most people put the window in 1st then just seal the liner to it 1 time. Seam tape alone even works.
I did mine same as you would with an epoxied tank by putting the liner in 1st. Its actually sealed 3 times. 1st in between the acrylic and the liner 2-4” around the permitter 1/4” thick. 2nd from the acrylic to the liner on the inside. 3rd on the outside liner to window as well with thick beads all 1/2-3/4” wide around the inner and outer permitters.
For the 1700 i put up i did bolt the acrylic in to hold it in place. Just 4 bolts tho. 1 in each corner. My 650 is unbolted. Both ways worked fine. It depends on the window seat u have whether or not ull need bolts or want to use them really.
