Abstract: A device 10 for applying constant pressure to a surface includes a cylinder 12 having a longitudinal axis greater than the diameter of cylinder 12. A first wheel 14 and a second wheel 16 are coupled to each end 18 and 20, respectively, of cylinder 12. Wheels 14 and 16 have a diameter substantially greater than the diameter of cylinder 12. An elastomeric covering 22 surrounds cylinder 12. Elastomeric covering 22 has an outer diameter substantially greater than the diameter of wheels 14 and 16. A handle 24 is coupled to wheels 14 and 16 for rolling and applying pressure to elastomeric covering 22.
