I need to get a set of new upper doors because my old sliders are worn out. I see a new set of Besttop sliders are $400 but for $700 I can get fiberglass sliders from a company called Bulldawg doors. Does anyone have any experience with these? I want to know if they're quiet and if they leak. My old half doors leaked bad during heavy rain. I'm interested in these because I like the look of them and I'll also be buying a hard top soon and they look better with the hard top than canvas uppers.
