Huge Update! All the "normal" vehicles are done. All that is left is 3 semi-trailer cabs. Some of the vehicles had to be power washed off at a local car wash as the temps were too cold to use my system.
Thanks. Yes, the job is pretty much over. I do still have 2 semi-trailer cabs and 1 International Stake Body Delivery truck cab left to do, but we are waiting until warmer weather to do them.
Definitely use the before/afters to advertise your efforts. Definitely takes some guts to tackle this, but it has paid handsomely monetarily and business-wise as you said you have followup work. Congrats!
