Looking good!

Just looked up the melting point of coroplast - 320 degrees Fahrenheit, much hotter than brakes or wheels should ever get. I guess maybe I'm just a little overly skeptical from when I had that one trip with a dragging brake caliper that made the wheel very hot to the touch until it got replaced.

So looks like now I'll be doing smooth white (a buck cheaper than black, so why not, plus soothes my OCD about heat absorption) coroplast discs then, with white tape over the lug nut and air valve holes for ease of access, and caulk the gaps around the edge of the rim.

Thanks for your patience and input with my questions! I'm sure I'll have more as I keep thinking this out and get my shopping lists made up.

Tryin' to hit 50 MPG by the time summer comes around.
