Cutting and refinishing a completed/cured sheet?

Hello all,

I need some guidance on how to modify an existing part. I have attached photos of a basic front splitter I've had laying around for some years now, and I was wonder if and how I could go about repurposing it. It is pretty flexible by my estimation so I figure if I can cut it into smaller parts, I could use it as front lip and side skirt extensions. 

For the front, it would require changing the contour of the front edge to match the bumper lip, and the sides would be rectangular strips cut from the back edge of the part.

How do I go about getting clean cuts, and how should the cut edge be treated or finished? I have zero experience so I would be looking at getting tools, protection etc.

If you were really worried you could apply a thin layer of epoxy resin to the edge.  Even superglue will work as a thin sealant or even brush on some lacquer carefully.  You could use a rubber edging trim to provide a bit more protection if required. 

Thanks Warren, will give those try.
