Guys who like broads with harry legs love Future Spa, because all that un-removable ball swirl in the flesh colored paint, makes for a strange attraction.
I found these pics from over a year ago, so I put up a quick guide. Because they are old, it's possible that some things have changed with the FS Hardtops. Consider it a snapshot in time.
I've installed over a dozen Hardtops, and have the process almost down to a science. The Outside Edge guys probably think I'm being overly critical every time I post about their products, but I just report how I see it. If I did not like the product, I would not keep using it, lol.
Here is a Comet I documented, read this for more tips that I won't repeat: https://pinside.com/pinball/forum/topic/vids-guide-hardtop-restoration-comet
