bungy 2 Posted January 14, 2011 Report Share Posted January 14, 2011 Has anyone got any experience of plastic welding and bumper smoothing? I've watched a few films on youtube and looked at the equipment needed but would appreciate any advice and recommendations for the correct type of rods to use and flexible fillers for finishing.

matty1990vr6 7 Posted January 14, 2011 Report Share Posted January 14, 2011 u need to get the rods that match the type of plastic in the bumper, for it to weld properly.also for ya flexible filler just go to your local paint suppler and ask for it.....cheaper then halfrauds lmaoand u will need a plasticiser additive u mix with your paint...this will allow the paint to flex without cracking. hope this helps Link to post Share on other sites
bungy 2 Posted January 14, 2011 Author Report Share Posted January 14, 2011 I'm happy with the need to match the rods to the type of plastic and I have got a good paint supplier near me so I will pop in and speak to him next week. Does the additive go in with the two pack paint? Link to post Share on other sites
dubbed_up_daz 8 Posted January 14, 2011 Report Share Posted January 14, 2011 when I done my mk1 bumper what I did was cut out a rectangular section of the donor bumper and cut that into 2mm wide strips and used that as a 'welding rod' along with a normal soldering iron.Used a similar technique to oxy-acet for actual work although the process itself is more like brazing with the speed involved.
