Bumper trim

I've got a Mk2 Nova hatch, and I was wondering.
The GSi and SRI have the red stripes on the bumpers.

My Nova is blue and I'm going for a White/Yellow/Blue/Black color scheme (IE, Blue car, blue lugs and valve caps, yellow brake calipers and drums, and white wheels) and such, and I was wondering what I could use to make that bumper stripe yellow, seeing as I don't have one. I thought about yellow electrical tape, but that won't hold very well.

Any suggestions?

halford do the 10mm bumper tape your after

Look for pin stripe on ebay

You want 12mm tape ideally, best going to a local vinyl graphics company and getting lengths cut to the size you want and they'll also have a better selection of colours too.
