You could probably paint over the herculiner if you want. I am doing it for sound insulation. If I were you I might try some herculiner and get some felt and cut it down the same as you did the quilt. Should be a very well insulated top then.
I'll keep you informed on the roll cage inside the half hard top. I am hoping it will be just what I have been looking for. I'll try to get some pics of when I install it and how it fits aginst the top. Just follow the link I gave in my previous post to look at it further. To me this it the best designed top that takes into account egronomics. It might not be the absolute strongest, but it is better than nothing. Plus, I don't have to have the strongest, that is why I am going with D44's and not D60's.
