I guess I'm approaching it from the opposite end. My thoughts is that $10 can maybe get me a a few degrees (a few hp, a margin of safety, however you want to look at it). And that's the cheapest I'll get anything like that on this car. I think your approach is equally valid in the "why would i throw $10 in the gutter for something thats toally unproven." So I think we're on the same page there. I guess I've just spent $10 on far stupider things, so in that way it seems like a bargain. (I tend to put small purchases in the terms of smoething like "a chipotle meal with guac", so in that regard i'd rather have some car stuff and eat a hot dog instead. And no tape is ever going to cure the stuck-in-traffic heat soak or anything close
that 10 dollars spent some people think of it as yea, ill drop a few degrees but like i said before i think it would almost add degrees instead of subtracting. thats my test hypothesis along with yea spending money on something not proven i somewhat agree with since we all buy into some hype depending on how much we want something. I've thrown money out before too so i cant be a hypocrite there. that and i can get down on some chipotle... the stuck in traffic thing is something that happens to the majority of so so thats what i base the bulk of my stance on. not only that but the majority of tape users that i see put it on without giving two shits on how it looks, have "the more the better" attitude when applying it so it looks ugly and tacky...
