this corner was the worst bit, the chip took out a few laminates in the timber, it had a prety hard knock at some point, anyways smooth as a babies bottom now, with all the chips, grafity, corners and edges all nice, its ready for a prime, and paint. back board just needs the vent holes cut out and mesh reinstalled. i turned the entire garage up side down looking for a hole saw. thats 2 hours of my life i want back and no bloody hole saw. ahhhhhhhh so a trip to the hardware on monday me thinks,
