Edit: there are liners that you can purchase for this. I don't know anything about them but I know FixedFiend uses them.
Yeah. Get the liners. Also, make sure you have plenty of pressure in your tubes. I used to get flats all the time until I figured out that 80% of them were so-called pinch flats or "snake bites" which are due to a less than adequately inflated tube getting pinched when you hit a rock/pot hole/curb.
