Not yet...thinking about it, though!
Please be very carefull, it is nasty stuff and can kill. Think about a full face respirator mask with the proper filters!!!! Check out ebay - $50-$100, some with cartridges filters. The fumes are not to be trifled with. Later (or before), the mask will be welcome addition when sanding or grinding fiberglass. Worth the money, I think.

I am impressed with your home work and planning. Prices sound a little on the high side though. If it is local along with worthwhile advice/knowledge, probably worth it rather than an expensive disappointment in the end.
