|I recently replaced the perished rubber seals and perspex in the windows of my RL 24. |
The rubber wedge strips used to seal the windows can be obtained from Grippy Rubber in Rydalmere, Sydney. They can match most sizes if you can provide a sample for comparison. I find the wedges more reliable than the various types of sealant on the market and a lot easier to install. Of course, if you remove the window frames, you still need to use a sealant between them and the coach house. I used a silicone based one with a short setting time so that it could be installed and screwed home without squashing the goop out and leaving capillaries for water to get in. It is also soluble in acetone which won't damage the perspex or the rubbers.
This has all been tested by a few good rain events and a near knock down that saw solid water going past the windows without a drop getting inside. I don't recommend the knock down test though.
Another tip: The old aluminium frames were also looking a bit, well, old with white patches in the anodising and a general loss of lustre. I rubbed them down with a rag dipped in Penetrol, which is a clear oil based paint additive (it is usually mixed into primers for painting difficult surfaces). This put a new low sheen coat on the surface and removed the unevenness in the colour with minimal effort.
So, now for the stanchions, deck fittings, rigging …
