Translucent coating on Canvas

I’ve got my canvas and will be applying it to my Walrus next week. I’ve been kicking around how to treat the canvas for at least two months. If possible, I’d like to stay away from painting the canvas as I’d like for the look of the canvas to show through and have a more natural earthly look than paint can provide. On the other hand, putting a clear coating on the boat will be glare city when the sun is out with the white deck.

So tonight, while at Fred Meyer, I went looking for a solution. What I found were various deck sealers and protectors. One type has UV protection, is mildew resistant, waterproof and has a mild pigmentation. Linseed oil is the base of one of the sealants. Has anyone looked into or used these types of sealant on canvas? I’d like to know before I drop 15-20 bucks on an experiment.
