All-weather seal retracts during insertion to prevent paint going up your barrel, then expands as you pull back to remove everything in it"s way. Molded Shaft - Not built on a twig, this beast of squeegee is forged out of tough & flexible plastic. All pieces are 100% interchangeable and 100% replaceable.
