I would only suggest Kelvar if one felt part was going to be abused in use, and separating from the car would be a bad thing after contact. In the case of a hood that could be good or bad. Kevlar is not as strong as CF, just a lot harder to separate after failure, where Cf will mainly shatter when it fails. A single layer of Kevlar with the CF is not a bad compromise, I do it often. twocents

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
