stan's tubeles convertion kits

Any hints on using convertion to tubeless with the stan's kit. Attempted it today and it didn't even nearly seal between the tyre and wheel. I'm not using tubeless tyre's. Even left it for a while to dry.....Any help !!
These manufacturers (non-UST tyres) are not compatable with Stans strips

You have to follow the exact instructions on the back of the box....use the "yellow" tape to create a tighter fit for the tyre bead. With some rims you can use the existing rim tape (see website).
You also may have to drill the valve hole in the rim as the rim strip valve can prevent the bead from sitting on the rim properly but this depends on the type of kit you bought.
