2010 vs. 4201
What is the difference? I see they have different ratios, but each must have different purposes. I'm looking for best option for frame of vehicle and maybe inner side of panels and fenders

I noticed a search for, 2010 brings a lot more posts than 4201

2010 is basecoat which needs to be cleared. 4201 is single stage, no clear required.

Black epoxy is what I would use for frames and inner fenders.
