its not the blue,,its the polish job...no cold blue will do a decent job except on small spots such as sights or screws. Otherwise, the entire gun needs to be polished to give an even color, and THIS is what separates the gunsmith from the amateur. Lots of good guns get screwed up by buffing and rounding corners, trying to make a gun look better. Better to spend the $$$ on a pro, or leave it as is.
