Last night I did quite a bit of research online, and I decided to fall back on my original plan for the wheel wells before I had decided to do them in high gloss black POR-15. Originally when we stripped the wheel wells, I had two options: 1) replace the factory-style undercoating, or 2) try something different and go with high gloss black. I decided to go for something different, and everyone knows the ending to that story...
Prior to deciding on using high gloss POR-15, I had researched online and found 3M Automotive Coatings makes a heavy duty rubberized undercoating as part of their Bondo line. This is what I would have used had I decided to replace the factory-style undercoating. Fast forward a couple of years to us once again having to make wheel well coating decisions. POR-15 had introduced their own line of rubberized undercoating, and when it came time to undercoat the primered wheel wells I thought the POR-15 undercoating would be a better choice.
After last night, I decided to fall back on my first idea. Sara and I had breakfast and then went to Menards and purchased cans of Bondo heavy duty rubberized undercoating. Each can cost only $4 compared to the $20 POR-15 undercoating.
