There are several ways to attach the side louvers. Some people use silicone, others use Velcro, and some simply fiberglass them in. Due to an act of stupidity (I accidentally threw out the supplied side louvers with a box of garbage), the louvers had to be replaced with an aftermarket brand. These replacement louvers use mounting brackets, which we have decided to bond to the body. We can use double-sided tape, Velcro, or other fastening techniques between the brackets and the louvers themselves. For now, we mark where the brackets will be mounted with a permanent marker.
