Can anyone relate experience with that stuff?

Yes, I can. My friend had a 100sq ft roll of this about a year ago and did a lot of his car and gave the rest to me. I did some of my trunk and both my front doors with it. I dont remember it having a very strong smell. It was a while ago though and i dont really remember. And I imagine that if it did smell bad, that is something that I would remember. If it did at all, it was only for a few days. There is no smell at all in my car now though, (well, at least not from this stuff). Typing when you're drunk is really hard. Writing complete sentences when you're drunk is also hard. Sorry in advance if this post doesn't make sense.
