Just to report that I finally broke down and got a spray-on bedliner applied to my RTV. I ended up going with Armaguard (which I gather is called Ameriguard in the USA). Choices this far north are limited, but I have to say that I am impressed by the outcome so far. Will let you know how it holds up. The guy who has the local franchise did a great job. With my help we had the 'bota in and out in about 2 hours and he only needed CDN$200 for the job (about US$170 today). Now I don't have to hold my breath when I am using the cargo bed!</p>
