Coated the foam plug of the largest section. Tomorrow it’ll get sanded then covered with mold release wax, though how long that’ll take depends how smooth the surface turns out, and how long each coat of wax takes to harden. If time is short then the first two sections – also coated today – will be sanded to see what’s what, or said another way, to see how many go-arounds of epoxy/micro and sanding might be expected before it’s deemed smooth enough to paint.
With both sections set aside to cure today, the car was warmed up (for the first time in a long time!), then an oil change done with full synthetic (mineral-based oil was used for break-in). The car was vacuumed out to remove as much foam dust as possible because I don’t want it blowing into my eyes while driving (never mind inhaling the stuff).
The last picture is a used “magnehelic” meter I picked up off ebay. It’s a very sensitive (1″ H2O) meter for measuring pressure differences, useful for testing airflow in ducts, intercoolers, radiators, but especially for determining proper placement for vents, measuring diffuser effectivity, airflow around wings, all sorts of interesting goodies 🙂
