Lower body panels...how to attach it?
 

Are they put on with clips or do they also require some glue or other adhesives too?

The reason I ask is that I recently got my car back from the shop and noticed it wasn't flush with the body. I mean its pretty much flush but there are some parts where one could slide the width of a key or something like that. (not that I did)

I thought it was held by clips and some glue.
