Ill ask if that's what he's doing, I just texted him to find out what chemical but it looks like walnut blasting is still by far the best route. Only problem is Ive yet to find one close to me here in springfield, mo
Hell Id drive 200miles to get it done

Im going to talk to him and see if he will do it for free if after doing it it hasn't done much of anything.
