I'm using something called Sheetrock 90 because I know it sands easily and sets up fast.
I treat sanding like a haircut ... it's better to go back if it's too long because it's too late after cutting it too short.
It's the radiused curved lines that are giving me a bad case of nerves.
I'll quit highjacking your thread now

Any time there is turbulence created in the rear of a vehicle, dirt collects. True for everything from panel vans to station wagons to certain spoiler designs. Turbulence = drag.
Hate to say it but that might be the best evidence that your car is a bit less slippery than it was before the spoiler...a pity really, because unlike many others your car is a true performer.

Correct. I don't want the trunk to be slippery. I want it to have a spoiler that exerts some down-force. I don't want to have a tall grocery cart handled spoiler with upside-down airfoil, so that means that it has to be on the deck, just like what I made. The turbulence on the back side is a downward pull. If I had made the spoiler a lot wider, like many cars have, it would have had a LOT more drag. It's a good compromise. I got the downward force without being able to suck Greyhound buses down the road behind me.
