a plurality of short channel bars positioned astride the assembly, snugly fitting and so spaced along its top edge that at least one bar is on each side of the assembly'"'"'s longitudinal center, one side of each bar being immovably attached to one support strip but not the other;

and

means for mounting the assembly.

2. The squeegee of claim 1 wherein the end edges of the support strips are turned outwardly to form at least a quarter-round.

3. The squeegee of claim 1 wherein the mounting means is attached to the blade/strip assembly with a clamp.
