I used pieces of garden edging as clamping pads on the canopy sides and covered them with clear packing tape to prevent sticking to Sika. Outlined Sika area with 3M fine line tape #218. Pressed tape down by hand then used old credit card to really rub it down well. Covered 3M tape with narrow black electrical tape. Finished by covering any exposed areas with blue tape. Used 3M, black tape, and blue tape to make edge line in skirt. Punched holes for cleco's. Final step was to put 3M tape on edge of canopy.
