Yes. I'd never let Rain-X anywhere near the workshop.

I'd also not use it on my car. I did use it once, and it worked
pretty well. Then it started to wear and the streaking was _awful_.
Once you've used it once, you really have to keep up using it. You
can't stop, and you can't clean it off.

After you apply it, give it 30 min. to cure and then wipe gently with
pure ethanol. No more streaking. BTW, for those who have to scrape
frost from their windows on a regular basis, rain-x is brilliant.
