Sticky Zoom on Tamron 28-75mm

Just got my Tamron 28-75mm that I bought off the marketplace. As I was playing around with it today, I can't help but think the zoom ring has more than a normal amount of resistance. If I try turning it slowly from 28mm to 75mm it will go a little, stick a little, go a little, stick a little, etc. When moving it a little quicker it's not as noticeable. I keep trying to convince myself this isn't a big deal, but it's REALLY annoying for making fine adjustments. The 3 pentax lenses I have are smooth as butter when zooming/focusing. This one, not so much. Focus ring is fine, it's just the zoom ring that's sticky.

Anyone else have this problem with the Tamron 28-75mm? Is there any fix I can do on it? Or would I have to send it in somewhere to have that done (or maybe a local photo shop)?

I don't think it should be sticky, but the build quality isn't a strong point of this lens (there way of keeping it cheap)

I have a pentax f 70-210 which seized and actually broke a part inside from trying to force it. I then decided I would pull it to bits and see what was going on. I got It back together again but I would highly recommend giving it to a shop. Primes are generally easy to service, at least the old ones are anyway, But zooms are something to give a wide berth it would have taken 6-7 attempts and HEAPS of frustration trying to get everything aligned again. I never found a replacement part for it but from pushing and pulling the barrel out it works very smoothly.
