This may seem a bit mad but I've over the last couple of years been using 3 in 1 oil and last couple months been using wilko bike oil in a little Gray bottle, My rapid stock had some work done on it a good couple years ago and needed oiling, Using the above stuff the stock has a really lovely Finnish, My mate has had some really nice quality stocks over the years and still reckons the stock on my mk2 rapid is the best Finnish that he as seen on a stock,
