We have a FWC Hawk Shell on order, and need to make decision on siding. I understand the differences between corrugated aluminum and smooth aluminum in cost, appearance, repair costs, etc. I'm interested in actual, real world experiences of those of you with smooth aluminum with scratches? Dents and dings? Warping and ripples? Ever need to repair? If you were doing it over again, would you go with smooth or corrugated?
