Thread: Dumb question time, bumper cuts for towbars...

Righto, never had to do this job before (as I usually don't fart about hanging towbars on poxy cars that have lots of plastic in the way). But, kids what hey - or more specifically kids bikes that no longer fit in said car mean that my beloved put in the order for a solution.

My solution is to hang a towbar on the thing for a bike carrier - which resulted in the expected "I didn't expect you to go that expensive" blah blah blah. But I managed to collar a brand new never fitted Hayman Reese bar with almost everything for $140, add the ECU module and plug cable for $107+gst&courier and the parts are worth about $300 which I didn't think was too bad.

Only part of this that is mildly concerning is chopping a 100x100mm hole into the center of the rear bumper to fit the new chunk of steel sticking out the back - any particular wise words from those of you that have gone down this route and chopped a bumper and not managed to destroy the paint? Measure x3, cut x1 obviously. Masking tape, and cut with a grinder or the like with a few mm spare to take off with a file or the like?
