I've just begun building the sail rig for a future Sperry; specifically a boom, gaff and mast. Per guidance from another builder (Christine DeMerchant, Canada) I'm building "birdsmouth" hollow spars.
Attached are some pictures. My question is on Interlux varnish - what can I dilute it with. The can came wrapped in tape and when I removed the tape all the text (directions) came off with it - I can't tell what's suitable for diluting.
Appreciate the help and any comments on the work.
