Hi all,
I did this after consulting with
Lewmar, the guys who made the hatches. They specified a silicone rubber
sealant with a specific number which I cannot remember!However I can say that the reference number of the
sealant was the same as the most common type of builder's silicone rubber sealant in my local store!Maybe your hatches are by another manufacturer, so it may be possible to visit their website to settle the matter?
Good sailing to all!
