Some instructions may be in order. clean hood.
1. seal just inside the inside of the hood with good tape (gorilla works well) 2. connect a solid piece of wire to the inside with tape 3. pour plastidip into a suitably wide container 3. dip and hang from wire top up. 4. cut out the tape etc and remove interior plastic by cutting and rubbing. 5 repeat if necessary.

I think you could get a much much better finish if you could thin the plasti dip and do multiple coats.
