We maintain a library of articles on the subject you are interested in. Open the web site below my name and open the P2Infohouse database. Searching for truck and wash gives you two articles. Searching for car and wash gives you 72 articles. You can also select Industrial Sector from our web site and then select Auto Repair and Fleet Maintenance. Many of the articles can be read or downloaded. I can mail you any that are not on line. Espero ayudarle.
