can be alot of work to repair a front bar, and paying someone to do that will vary depending on the damage.
when this is moved to the more apporpriate location, you'll get some more help.
i have fixed a few front bars, some with bits completely craked out.. can be tricky to get them to work back and remain invisible once sprayed.
post a pic for us to look at, but yeah. hard to say..
if you like that front abr, fix it.. fibre glass isn't to tricky if you work in small amounts doing a little bit at a time.
you can only try it out..
