I grew up around car washes and detailing, making me second generation and have been working in this industry for well over a decade. It is very much a love it or hate it relationship. This business chews up most within their first 3yrs. What I have seen as the hardest part is gaining the experience, it is the only way to truely be good at this business. Even with seminars,
education programs, books, and consultants that are available they are good at it because they gained the experience and most likely will not be there forever to help.
The biggest headaches come in 3 areas. 1st are customers. You are handling their 1st or 2nd most expensive purchase it takes a certain learned finesse to handle each one with their situation, which may or may not be valid but requires the experience and finesse to handle properly.
2nd are the employees (depending on kind and size). Good ones are always hard to find and keep at wages that make the wash competitive. Not only do you hire them but you hire their whole family, meaning any personal problems that arise are now your problem.
3rd is the equipment. Repairs and general maintenance are not usually easily found for this industry. If you are mechanically inclined that can help but is not always enough. If it is not enough then you enter the realm of a repair service and what their capabilities are with your situation.
So what is good about it? If you are self driven and always wanting something more or different then this is a good business. There is always something new. New equipment, chemicals, products, standards, competition, innovations, repairs, customer situations and some unforseen disaster that needs a creative solution. The people that work in this industry are of every sort imaginable, from all over the globe, wealthy, broke, traditionalist, innovators, tuff, mellow, brilliant, and not so brilliant. It is not discriminitory againsts anyone it loves and hates all equally.
