I'd be hesitant to use any of the Blue Beacons or any of the automated truck washes, they use too much pressure and also use what they call "brightener" which is a mild acid which will probably do damage to your graphics and possibly more.
I drove truck commercially for almost 20 years and rarely used a truck wash unless it was one of the "hands on" types where they've got a bunch of high school kids with brushes in their hands and having water fights...LOL
I used Blue Beacon once when there was nothing else available and I told them not to use their "brightener".. well, they did anyways and it took the polish off all the aluminum on the truck and gave it that dull appearance like it had never been polished to begin with.
I drove for MS Carriers for a few years and they were installing automated washes at all their terminals, well, they didn't have the pressure just right and it took large portions of the graphics off the trucks and trailers.
So, I'd say if it's a hand wash type, go for it, if not, you're taking a risk.
