I tried the pummice stone, it didnt make a dent. the Acid.... didnt work. I doubt you can see how thick the calcium is from the picture, but its pretty bad. I think blasting is the only way. OutColed, are you in So Cal? any recommendations?
Ill be at Desert storm this year and it will be my first time. Ill only be able to make the shootout. I have a 21 RC so please tell me where to go, or more importantly, where to stay away from.
