I’ve never had to sand it, but it did take some coaxing into place. It’s really easy to build a lop sided Thunderbolt. The floor pan will sit below the rocker panels, and when you look in the windshield, the tub will be really crooked. The very first one I ever built, I glued the tub in place, and I never glued another one after that one.
It’s one of my favorite kits to build, and I’m not In no way, knocking it. I still have a couple more planned, with the Reynolds car, and Atwater car. Actually I was working in the Atwater car, and I need to get another body, so it’s on hold.
