Undercoat removal

Hell yeah I’m going to try it. I got so much of that under coat on my car it’s 1/4 to 1/2” thick in spots. Unreal, problem is that it’s all cracked and now trapping water and cause problems.
Wish I had known that a few months ago! Removed the undercoating on my 67 Dart with an angle grinder and wire brush attachment. I just kept spraying it with water mainly to keep the dirt/dust factor down but found that wetting it made it easier to remove. I’ve never been dirtier in my entire life.
