NickLim

So i just purchased a set of Yoro Double Nickel satin and after one round, i noticed small blemishes on the iron heads. They look like scuff marks on the head. They can be found on the muscle pad (MP5), hosel etc. I have a set of Yoro MP 4s in Chrome satin and have never seen this on them before. Now, i'm not a princess when it comes to my iron, but just wondering if this is because of the double nickel satin finish... I use a push cart, and transport my clubs to and from car with headcovers. I don't use the headcovers when i play, but the clubs don't chatter that much or at all since i use a push cart. As well, im wondering if they are water stains as nickel satin is prone to them... If anyone has the double nickel satin finish, i would love to hear. Outside of that, the irons are awesome!!
