Back in the day, we used an epoxy finish on our over ther road trucks, because of the harsh conditions they were exposed to, as opposed to the softer fiberglass gel finish on my BH. The truck wash facilities because of what they were forced to clean, used some pretty harsh chemicals and reportedly abrasives, to get the trucks clean, and over time we would see the epoxy finish degrade. Personally I would NEVER take my BH through a commercial truck wash. We can wash ours in less than 45 mins., me on a short ladder doing the top half, and DW on the ground doing the lower part, and I KNOW what's being used.
