Arrived home to a surprise today... the Race Technologies DL-1 data acquisition system came in a day earlier than it was supposed to...

Anyways there is one little issue - the GPS antenna is a magnetic mount while the camaro's roof is "plastic" over metal backbone, I just tested it and the magnetic field is too weak as is. I have an idea what to do though: I want to powder coat and epoxy a thin steel plate (0.0625" to .125") shaped to the receiver outline onto the roof. Has anyone done this before? Anything in particular I should watch out for when doing this?

You can probably strap it down with non metallic tape. Or, see if it will function properly through the rear wing of the Camaro, you could hide it inside (if it's sensitive enough, and there is a good chance it is).

just get some 3M auto adhesive tape...you don't see your emblems falling off do ya?

That stuff is wicked. If you are not planning to remove it, that's a great option.
