Dan I have no big problem removing bugs and the bug print from the surface,tho this time of year some are stuck on pretty good.I never haveta brush the bug print off chrome like some do and can remove them about as fast as I can move the wand across them.
Yes Tony I use the same soap to wash my personal rides,I'm also picky when I wash my trucks and vettie.
Yes unless they have been repainted all trucks have clear coat,like cars some have a better paint job.Some F'liners have a piss poor paint job,oil and stack juice will inbed in the paint which you can remove but a shallow will remain in the paint.
Brushing and mitting are for those still want-a-be truckwashers,lol,I have trucks I've been washing for years and they have no brush streaks.If I had to brush I'd fine a different trade to get into,it sounds like to much work.
Tony to help with the fear of damage to your pickup I even 2-step some of the pickups I wash,which is a acid wash,Paint nowdays is more like plastic.
