So is the trick to use the right compound, then drag?

I remember last fall at the Dutch, I saw a lot of scraping at the starting line and can't say there was much of that if any last weekend. So I guess there's a sweet spot for the right amount of rubber as well.

So again, what's ideal for a Stocker and higher HP cars (excluding nitro) that works for both?

From what I've seen and read, dragging the track is most times more important in terms of frequency of its use vs. spraying the track. Too much spray results in the upper rubber layers coming up to easily resulting in tire spin. Dragging in a sense helps the rubber bond with the surface allowing the tire to grab the surface instead of pulling it up. The other part of maintaining the surface is having an eye for rubber build up in the first 200ft or so of the track surface. It needs to be scraped when this happens. I believe those are the keys but I'm sure there are many more nuances to the process. Somebody please correct me if I my thoughts were incorrect.
