Auto Paint Training – Sealer and Base Coat

In this video we’re going to discuss and demonstrate how to spray primer sealer and base coat. We have already prepped an OEM fender by sanding with 500 grit on a DA with a soft pad and surfing the edges with a maroon scuff pad.
Method 1
Painting the part before it is installed onto the vehicle is one of two methods that we practice at Butler. This allows the painter to paint the part with less masking, which makes a smother and cleaner finish. The problem with this methods is that care must be taken when installing the part without damaging the new painted surfaces. Normally, adjacent panels will still require blending to provide an invisible repair.
Method 2
The second way that we practice is to edge the panel, then install it on the vehicle. Then the panel is masked with the blending area and the panel can be painted while blending the adjacent panels. This makes panel alignment easier and any scuffed made while installing the panel can be easily repaired during the refinish process. Both methods are effective and have pros and cons.
