Spoiler Question...
 

Figured this would go in the General section... Well I took a spoiler off a 3rd gen maxima, and I want to get it painted. It feels like it's made out of this foam material, and I think I heard some people say it was. Should I get it fiberglassed before I get it painted so its a bit stronger on the outside?

Should I prime it before it becomes painted?

And last question... When installing the spoiler, I don't have holes in my trunk, whats the best way to install it?

Thanks in advanced.
