Spray-in Bed Liners: Your thoughts?

[ButtersTheTruck]

Hello all

As some here know, my 1967 C20 is a working truck. I got her mostly for farm work but I also intend to take her to some shows, just for fun (she's neat and in really good condition but I don't have the money to invest in her to make her a mint show piece). Mostly, she'll be on light farm duty getting hay for me.

Because she'll be used for hauling (hay and feed in her bed and eventually occasional horse trailering), I have been considering getting a spray-in bed liner to protect the bed. My dad has it in his 2007 Toyota Tacoma and it's really, really nice. Makes cleaning super easy and it's durable material so it doesn't scratch unless you really put some effort in.

I waffle because I am concerned doing such a thing would make my truck totally worthless and an embarrassment to show. At this point she is all original and has a little over 43k miles and is nearly rust-free. So she's a little bit of a rare bird as she is.

I do not intend to ever sell her, or if I do it'll be a long time down the road after I've used her for many years.

So what do you think? To spray, or not to spray?

Here's the truck, in case you're interested
