I wanted to get my static system in before putting the rear skin back on, but didn't have any pro seal to do the job.. This is a bummer because such a small amount is needed I didn't want to buy a whole new tub. Luckily, I was able to borrow some from a fellow builder just down the road which was just perfect for my situation.. Basically for the install, I cleaned away the primer around the 1/4 inch hole, scuffed up the surface of the skin and the surface of the static port. Then using a thin layer of pro seal I mounted both ports on each side of the fuse. I drilled a hole in a small block of wood so that the port was unobstructed, then used a clamp on both sides to ensure pressure while it sets up. Looks good and will have a definite seal since I drilled some holes in the port to ensure the pro seal got a good grip... I am concerned though because as I screw on the 90 degree fitting for the static tubing, it needs to set vertical for my plumbing run. I just attached the ports with no concern of where that 90 degree fitting would end up when it is finally screwed in. I hope there is some wiggle room tomorrow when I test it out..
