Recently had some body work and repairs on my 38. I replaced the rocker panels(coupe) and the quarter panels. There are no drain holes in this new sheet metal. Should I drill some in the rockers and quarters to allow trapped water to exit car? If so, should these holes be protected by small rubber flaps? Interested in what others have done.

My original sheet metal in those areas were too far gone to determine how Fisher handled this issue.

Appreciate any insight.
