Under body Color - Speed Yellow GT3

[petercory]

The paint in the L.F. wheel well of my '04 GT3 was damaged by brake fluid when the prior owner installed Club Sport Motons. The exterior of the car is Speed yellow, however the underside is not; it almost looks like a white with a yellow tint. Can anyone provide me with the color code or paint mix for the underside?

Most Porsche underbodies are overspray from the painting of the exterior body.
What you are seeing is probably the overspray on top of the original underbody seal or stoneguard.Usually the underbody seal is greyish or sometimes beige in color.
You can duplicate this provided you can determine the correct color underneath and then spray your yellow on in such a manner that it only fogs on due to the angle and distance of the spray pattern. If you look closely at it you will be able to determine what angle and direction the paint came from that hit this area of the car while the body was being painted.Then,just try and duplicate that scenario.

The wheel wells and the under body seem to be a pretty consistent light yellow; there is no stone guard applied (perhaps because it is a GT3) as opposed to my '84 030S which ( has stone guard/body schultz applied in the wheel wheel wells as well as to the floor pan) which are also the same color as the exterior of the car.

In this case I believe your best bet would be to take the car to an Autobody paint supply store and have them do a color match on it.Get it in a polyester basecoat.Some places can put that in a spray bomb for you if you're not able to spray it professionally from a gun.
