xinitialz, you are not right.
The first version of the JMS front spoiler was made of GFK/fiberglas. Now they are selling a version made of PU-RIM.
I am lucky to have the first version made of fiberglas, so it was easier to make it look like a one part frontbumper.
You can easily reinforce fiberglas parts like i did, so it is able to resist speedbumper hits.
