Common Mistakes: Body Filler On Bumpers
I-CAR · February 25, 2019
Summary
This article highlights the common mistake of using metal-specific body fillers and glazes on plastic bumper covers. It explains that because bumper covers are designed to flex, technicians must use flexible plastic repair materials, such as two-part epoxies, urethanes, or acrylics, along with proper adhesion promoters.
What to do on the job
Never use metal body filler or glaze on plastic bumper covers; instead, use flexible two-part plastic repair materials and the appropriate adhesion promoter.
How to use it
Use this document to justify the line items for specialized plastic repair materials, two-part adhesives, and adhesion promoters on an estimate or supplement, rather than standard body filler, by proving that metal fillers will crack and fail on flexible plastic substrates.
