Hi guys... Great job am on the same boat right now... And same windows... No butilic tape between windows and van, just silicon? Thanks to reply... All the best Max
we didn’t originally use silicone, we just went with the seal that already comes on the window but realized that wasn’t as water tight as we hoped so we took them back off and ended up using butyl tape! if you find waterproof silicone, that could be fine, we didn’t look for it because we already had butyl tape available! feel free to message us on instagram if you have any questions!! 😊
