Swiebertje – I’m very interested in why you dislike silicone so much. Because I used it when I refurbished my bailers. Could you explain why please?
I used some “Evostick Nails and Seals” from B&Q on the slot gaskets, as per your recommendation in Mike Macs slot gaskets article. I think that this is the UK equivalent in the MS Polymer that you recommend, i.e. a cheaper slower setting alternative to Silkafix.
However, I didn’t use this on the bailers as I thought it would stick the bailers to the hull and make the bailers very hard to remove in the future.
So far, with the silicone and a few Grolsch bottle tops around the centreboard bolt – the bottom of the boat is staying pretty dry!
