I used a similar sized roll of masking tape to judge how dented up my gauge buckets were, then hammer and dollied 'em back into shape. Also the gauge bodies in primer. I decided I'm not spending any time on new gauge faces...it's very time consuming dis/re-assembleing those gauges, they work alright, and I don't mind an old bike showing it's age here and there. Every once in a while I will see beautiful women with grey hair.
