A couple of weeks ago I asked on this board about the pinhole leaks on the A/C high pressure hose (my car is 1996CSE). There are actually about 10 pin sized holes on the high pressure hose. When the AC is running, oil comes out of all of them. I appreciate all the suggestions given by many members here. Here's an update how I fixed them really easily.
First I asked for an old bike tube from a bike shop, then cut out 10 round pieces the size of a dime coin. I then clean all the round rubber pieces with brake cleaner.
Second, I cleaned the high pressure AC hose with brake cleaner by spraying directly at the pinholes and let it dry for a few minutes.
Third, I dropped one drop of super glue gel on each of the pinholes, and pressed a round rubber piece over the glue. Repeat for all the pinholes. I didn't use any clamps on the rubber pieces.
After doing all the above, I waited 4 hours, charged the AC with a can of R134a. The A/C became very cold, and the glue seals very well. Now it has been three weeks and 2000 miles, there's still no leak at all.
I hope my experience turns to be helpful to any of you with similar problem. It takes 20 minutes to fix (including the time driving to bike shop, I did the fix in the bike shop's parking lot) and only costs $2.50 for the super glue. I guess it's always worth a try before going for more expensive options.
btw: I used the Super Glue Gel type instead of Super Glue. According to the instructions, Super Glue Gel allows a larger gap and works for rubber and other porous surfaces, while Super Glue requires a very small gap and only works on very smooth surfaces.
Here's a link of the Super Glue Gel I used:

BTW as an added bonus, the glue works perfectly on fixing my wife's shoes :-)
