It's been soooo long since I made a plastic cowl, but I would be more inclined to go that way, then the papier mache...I would use a wood plug, sanded perfectly smooth, and use the stove, to finish it...I can't remember the temp I would use, but if I remember it wasn't very high...if you email me and remind me, and give me a few days, I will experiment a bit, since I still have some plugs, and the plastic....I do remember it was a LOT lower temp than I would have expected....

I have since graduated to fiberglass, and it's really easy, since you are making a wood plug, anyway.

There's a good site on fiberglass cowls, on one of the other forums, here:

Good luck, and most of all, have fun!!!
