Hi all,
well the paint shop finally got to the problem..whoever did the primary repair to the bumper did not use the correct glue/adhesive to repair the crack. Now it keeps moving apart whilst in the bake oven( or shortly afterwards )
Please can you tell me exactly what I need ( and where to get it )to mend/glue my front bumper. The crack is only 3" long and very fine.
help please, here in the Uk I cant find anyone who knows this stuff??
