This is the very first Overspray Removal Certification that will be offered to the public.  Overspray jobs are unique in that the independent detailer or business owner is no longer doing one car at a time, it can be projects that are 20-1,000 car projects.  We want to share our knowledge, tips and tricks with you on how to safely and effectively remove various types of overspray/contaminations from all common types of vehicle surfaces.  It's taken us 40 years to accumulate this knowledge and we want to share it with you.  

The one and a half day course will be led by overspray removal innovator Jim & Eric Gerencser and Texas detail legends Carlos Serrano and Gilbert Martinez.


Serious independent detailers that are looking to grow their business and skill set.  The overspray business can be highly lucrative due to the volume of potential vehicles.  With the Overspray Removal Certification you will be invited to join the Nationwide Overspray Network of business owners.
