Hi,
We finally got some sunny days and negotiated some time to clean the car

I did the whole thing, wash , clay, wax, wash the carpet...
I used Rejex and it says on the bottle that it should last 4 month even through car washes.. However it's not clear what should I use for washing my car. Can I use one of those washing liquids from Mequiars or ArmorAll? will they removbe Rejex? If not what will remove Rejex?
Also I'm thinking on getting a second key, my keyfob stopped working a while ago. Can I use 997 keyfob for 2000 Boxster? They look nicer and seem better built that 986 ones.
Also will I have to reprogram both keys? or can I just add one to existing key?
I'm thinking of buying Keyfob from Ebay (the one with the long number) and let Stealership do the programming
Thanks
Sasha
