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. Type of front contour Existing part

You'll find loads of generic ones on places like eBay for around £8 and these work just as well as more expensive branded ones You can opt to go for some of the Permagrit hand tools for finishing and smoothing your cut edges, but if you didn't want to invest in these, some coarse paper on a block (60/80/120 grit) will also do a good job of smoothing things down

Now that you mention it I do believe I have a Dremel tool with the flex shaft extension Is there any need for a sealant or epoxy on that edge? Considering the parts will be mounted at the lowest parts the car I wonder if water penetration is a concern for the sanded edges? Edited 4 Years Ago by Rival876

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.
