You can get can-o-webbing but it is thicker than the original but an alternative for you.

If first time webbing no matter what product/method you decide to use very important to PRACTICE first on a pc. of wood/cardboard/etc to get used to the pattern/flow/technique of the webbing.

1st time I used the can-o-webbing and then thru a friend I learned how to use a automotive spray gun which really is the best to replicate the webbing. CLay shows ho to some what replicate webbing by using a small wire brush....which you've probably already seen. Don't confuse webbing w/ splatter....splatter is the 'dot's' Good luck.
