removing undercoating

Here is a video of the larger needle scaler from Harbor Freight. I used the mini version since I was only doing a portion of my floors, seems it was around $20. A decent compressor will be needed for best results. I cant say mine came off as easy as the undercoating in the video but it will make short work of cleaning it off. Careful in rusty spots if you have any, mine was a little rusty under the heater box where the floor angles up to the firewall.
