I don't have a "real" welder - I use a soldering iron (but NOT the same tip I use for soldering). Finding matching filler material can sometimes be tricky. I have better success if I can work both sides - which may be hard on a rain barrel. Like any other welding, clean is good. Heat both sides of the crack until it's molten - but for most plastics no more heat than that! Heat the filler with it, pushing the filler and the base material around to get the parts to flow together. Often it's helpful to apply pressure as it cools. A screwdriver can work. I find it much easier to weld metal. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
