Looking on starting a detail business, I've been working on cars for as long as I can remember I can paint and service even the most difficult (I own 3 Audi's), I already have jobs lined up and have completed several details with great results including paint chips, but my biggest concern is I want to be mobile in the most compact way and was wondering if using a steamer would be a good replacement for using customer's water supply or should I invest in a quality carpet extractor. Being a painter I am pretty well stocked in the finishing end of supplies and know-how.
