Hey fellas,
Whats the best pen/ marker to get a game used Rawlings Cool Flo helmet signed? Its a black helmet.

I may get a Orange Helmet signed too, but I think a Black Sharpie is best for that.

Some details:

I'll be going to spring training to get is signed, but the player in the past has taken his time on his autographs and doesn't seem to rush. I assume his sig might pool if it's a paint pen.

It'll be probably 70-80 degrees, I've heard in cold temps some pens are junk.

I'd like to avoid a silver sharpie. A helmet I once saw had the autograph just smear off even years after it being signed. Luckily for my friend, he wanted it gone.

I've also heard of some people charging or juicing their pens prior to use, What the heck is that? Are they giving it to Canseco to get it in good enough shape or what lol.

Thanks for any help. I only get one chance to get this signed right, I want it to count.

I put some sentences in bold for those who want the cliff notes version of my post.

THANKS!
