Fiberglass bodykits?

what sounds better "With Multi Layers of Super Thin Fiberglass Mat to ensure Strength and Flexibility" or " 7 layer of superior quality fiberglass?" im leaning towards the 7 layers atm, but any info would be great :)

7 Layer. Multi = anything larger than one. I prefer actual numbers when I look for products :)

I personally like the 7 layers one. The multi layers of blah blah blah seems a bit too long...
