Hi there Dingfixer!
I am sorry if I am too late to comment and make recommendations, but we actually just refit
sides and refurbished all of our portlights
. Just got some rain last week and we no longer have any leaks! I am happy to answer any questions you have regarding portlights
and sealants, or you can check out our last video upload which shows exactly how we did it. Check it out on YouTube @SVAvocet. I hope this helps, please feel free to email
if you have any questions!
Marissa + Chris
