Used several tools to include: popsicle sticks, plastic scrapers, magic erasers, razor blades, etc to clean off excess Sika from frame. Not as easy as I hoped, but the resulting edges are nice and straight. Marked the sides with tape for the top of the outside skirts and cut/sanded the squeezed out Sika and sanded the canopy side to prepare for attaching the skirts with Sika.
