Should I use the bolts that came in the box or not? The rear, what to use to hold it in place other than 3M, anything else? Should I fit it first before painting and do the the required holes, or should I wait until it is painted?

Thanks

 

It's always best to test fit it first. At least that way, if any minor modifications are necessary, you can do it before the paint is applied. Also, it ensures that after the lip is painted, that it won't be damaged when trying to re-mount it.....it should fit already.

 

I would use the nuts it came with...also i didn't us any 3m tape on the rear one...i only used it on the side skirts
Mine hangs just a tinny bit in the middle on the rear one...i would just put a little bit of 3m double sided sticky tape on the middle of the back one

 

I used the rivets (inside the wheel wells) that came with it and some of the tape just for overkill.

 

I used body screws that I got @ the stealership in the wheel wells. This makes taking the lip off easy. Living in the northeast this is helpful if for some terrible reason drive her in the snow, and foglight bulb replacement is a snap.
