Just using straight linseed oil, will not give you the finish you want. I've used it on very few applications. My go-to is still True-Oil but gees, there are literally hundreds of finishes that will work for you. One negative about Tru-oil, is that it is only available in a high gloss finish but you can tone that down. One thing to look out for, is standing up to the weather. I refinished Tru-oil stocks that have seen many Iowa winters and it's still going strong. I don't think you can say that about other finishes. Just make sure it's rated for exterior application or keep it waxed. ....
