And I would term it a success story...

It took about about 20 minutes or so following JMCraney's instruction. The interesting part is that there seems to be a gasket made of silicon sealant inside of the triangle piece similar to Jmcarney's pattern and in one of the edge of the triangle piece (inside) there is some bush like material that try to cover one of the crack that JMCraney pointed out (the one label 0.4 gap in Jmcraney's picture). So my guess is that for some LS (my car is builded in June 08), Lexus tried to implement the same idea that Jmcraney has with various degree of success.

Anyway, I let the sealant dried overnight and test drove about 20 minute this morning and drove on the freeway for about 2 hours tonight (speed vary between 70 to 90 mph). The "washing machine" noise that my lexus mechanics described is gone. I still hear some very low and muted wind noise in the background but it does not bother me anymore. And one of the really nice benefit is that I don't hear any engine noise or tire noise from the car in the next lane. When I first picked up my 08 LS a few weeks ago, I was surprised that I could hear a lot of differnt mechanical sound generated by another car when it passed me in the next lane. I don't hear any of those sound anymore and it make for a very quiet ride on the freeway (except my own tire and engine sound, of course).. The clincher is that my wife drove the 2nd leg home tonight and she proclaimed that the LS 460 is as quiet as the 02 LS 430 that we had before (she was the main driver for the 430, so she know the car a lot more than I did) and I can turn on the music with a lot lower volume and still hear them clearly.

Thanks for the triangle idea, I can fully enjoy the LS now..
