It's alright. Most big Home Improvement stores sell it in the paint isle next to the spray paint. It comes in a can you can dip or pour or it comes in a spray paint like can to spray it on. It is a liquid latex rubber that made it's mark as a non slip heat/cold resistant coating for handles on hand tools. But, it has so many uses! Many Clones in the 501st use it to paint the black band on their helmets. i found it works great to strength thin vacc'd plastics. If you get the can type, you simply pour a small amount on, slosh it around, let it set and repeat a2 to 3 times. They should all be thin coats so it dries faster and more even. If you get the spray type you spray 2-4 thin coats on. It adds a bit of rigidity and helps prevent tears on edges. Also, if you drop them, they drop crack or split, they bounce... seriously!
