Somewhat of a performance topic, but more cosmetic I suppose. This is more of a DIY know-how post anyway.
Finally decided to go after the SC cover on the SLE. I've wanted to mesh it like the SSEi'* for a long time.
I drilled with a 1/4" bit in each corner of each intended cutout, then roughed in with a 3" pneumatic cutoff tool. Finished the rough cuts with a dremel, then used a sanding drum on the dremel (1/4") to finish off each window.
Lightyly sanded and de-greased the entire thing, then used some of the cutout material to re-build my two broken clips and repair a crack:
Tonight I'll wet-sand down the letters and numbers to expose the plastic color, then sand off the overspray underneath where the adhesive has to hold the mesh to the plastic. Then I'll pre-cut and shape each piece of mesh and glue it in.
