Advertising...phone book?

Ah-no...exactly how would you do that anyway? Turn the pressure off and kill the engine before loading... most buckets have lids. Your vehicle & trailer signs are the best advertising there is for the $$

Never happened to me in 8 years and our logo is prominently displayed. We've gotten thousands of dollars worth of work from truck/trailer logos. for us, the assets of having logo on the trailer far exceeds the slight risk of somebody making false claims of getting paint on their car while going down the road. (Especially if your paint is stored.) A frivolous law suite is more apt to happen when striping, not while traveling going down the highway. That one did happen to me recently, but my attorney took care of it with a letter warning of possible repercussions from frivolous lawsuites.

Your equipment is less likely to be stolen if your company name is plastered all over it.

Good point Rock. Losing a trailer full of paint machines?!?!?! ....(((shudder))).
