Stick on Walnut Effect Trims For Dash!!!!

Has anybody tried the stick on trim enhances that are being advertised on e-bay?You can get them in Walnut/aluminium effects etc.If these things are any good i quite fancy trying the aluminium effect ones.They stick on around your heater outlets and the central dash area.

I got a woodgrain look kit the deluxe kit with all the trim pieces including doors/speakers overhead console ect ect ....
Preperation is key to get them on to stick well ... plan on cleaning /cleaning/scrubbing/rubbing especially if you have used Armorall or other dash protectant (especially those with silicone) I highly recomend 3M adhesive remover followed by 3M adhesion promoter to install them ...
I've got a carbon fiber set on my car (installed in 98) and still looks perfect ...
