Answer to my own question; Lesson learned the hard way.
Well, I have to say that 1900 PSI is too much pressure, although its great for wheel wells and tires.
Thank God this happened on my truck and not a customers:
I was rinsing off some dried mud and the 1300 PSI nozzle wasn`t working so I switched to the 1900. I figured that since it worked safely on the tires and wheel wells, why not try it starting at a "safe distance".
Well all of a sudden "Dakota Sport" became "Dakota Sp t" then
"Dakot S ". The vinyl decals on the doors (which had a couple little pieces that were gone anyway WHERE COMING OFF!
So I had to remove them all and get the 3M adhesive remover out and repolish and wax.
I never liked them much anyway, but boy did I learn a lesson!!!!!
