I was just about to say, lexan won't hold up very long. And IDK if this matters or not but my fogs are curved. Not sure I can just run out and replace it with flat glass.
Do they not make clear silicone or why did you use black?
Good DIY though.
IDK, I used Lexan on my fog for 2 years now. Never had a problem with bubbling or anything. I know that regular plexiglass definitely cannot hold up to the heat and that is why I went with Lexan.
