Kams, Do you remember what brand of body filler MCR used? I just remembered that in 1978, I bought a 1966 Hemi Satellite that was solely drag raced from the day it was bought new. The rear wheelwells were radiused for slicks. I sold it in 1982 when gas hit $1 per gallon.(stupid me!) In 2005, A friend of mine found it in a field, buried up to the rockers in the dirt...in Buffalo, NY. He bought the bare body shell for $800.00. The filler on the wheelwells was still intact! When he tore into it, it was on there very thick...up to an inch thick in spots, and that was filler with the quality and technology from 1966, and covered with laquer paint! I wonder how the filler survived under those conditions, for that long of time?
