just received my new sunlighter bikini top today in the mail but can't install it yet cuz it's been raining cats and dogs all day
but it looks to me like it'll keep you dry, but even better would be a safari top for drivin in the rain since that covers the entire top, you def will keep dry with that (and ur stuff in the back too).
...it looks like it wont be too much to install it, but it's not as easy as i'd want it to be, you have to install a channel across the header with screws (depending on your year i think you might have to drill holes for the install) so that you can insert those plastic driprails or whatever they're called underneath.
on my search through the threads i came across this link, it outlines a bikini top install. thanks to whomever did it, i hope it's ok to post it here.
