True
BDC, it can't hurt.
But the poster in the thread from several weeks ago was pretty clear that even most race cars would not benefit from a waxed surface versus one that was rough and pitted.
I asked him if he could tell me the speed at which drag from the condition of the exposed surfaces would come into play and he said it wasn't quite that simple ... actually depended on a number of factors. I came away thinking of speeds in excess of 200mph.
I looked for the thread for about 20 minutes ... but I just can't think of his name nor any key terms used in the thread.
