The door seal on my ES-P has sprouted several = pinhole leaks in the region where the two ends of the tubing are joined = together.  I contacted the manufacturer, and was told the seal is = made from layers of dacron and silicon.  This repair procedure is = my adaptation of what he told me about fixing leaks

Lightly sand = around the area of the leak
Clean area with acetone
Poke some rtv = silicone into the pinhole.  I've found that a toothpick works = well.  I've been using DOW 3145 adhesive/sealant.
Let the rtv = fully cure
Inflate the doorseal with the door open, keep inflated for = the following steps
Spread a small amount of rtv around the area of = the repair, and press a small patch of peelply into the rtv
Spread a = bit more rtv over the top of the peelply to seal the peelply and its = edges.  An ice cube works well to smooth out the rtv & peelply = combo
Keep the seal inflated while the silicone dries

The = initial poking of the rtv into the pinhole fixes the leak.  The = application of peelply keeps the inflation/deflation cycles from = reopening the pinhole.

I've repaired numerous pinhole leaks in my = plane's seal; these repairs have lasted so far for 200 flying hours...no = pinhole has reopened yet.
