Eelco.......this is only the secound time I have tried cobbwebbing,,,,,,but the way I did it was......I bought a touch up spray gun used for real cars......they use these to paint door jams......I put un-thined black lacquer paint in the gun and shot it out with high air pressure ......around 45-50 psi......but you might want to practice with the air pressure till you get it right......it needs to come out stringy ........like little worms.......let it dry for an hour then when you shoot a clear coat you need to mist on the first coat or the clear will eat the cobbwebbing......thank`s John
