Doug...I hope you aren't referring to someone at my shop, let me know if you are, and I'll set them straight. The only problem I've had with the tops is that sometimes, you can crack out the paint on the corners, IF the fit is really tight. If you have to 'force' the top down over the frame-rails, you can spider-web the paint on the top. I suggest painting it attached to the frame (if you can) that takes what I described above off the table. Other than that, there is no problem painting the fiberglass, we use them a couple times a year and when they are done, they are gorgeous. You have to thump them to see if they aren't metal.
