Working on base for roof rack. I have the sides of the rack custom fit to the shape of the roof to be on top/inside of the plastic skid strips. Each side will be bolted down to each existing skid strip mounting location (not shown in pics). There will be no rails.

Does anyone know where I can get weather stripping for 3/16" material? The pressure will be only on each side, but I may want to run front and back strips also minus room for water drainage - tight but no presure to the roof.

Each skid strip already has a gasket under it, but I'm not sure if I'll be siiting on that or not. Depending on how I mount the rack, the plastic skid strip may or may not stay.
