A bit of the white paint from my plastic side strip has come off when power washing with a car was power washer.

This has left a black mark around a couple inches long on the side. Whats the best idea to fill it in or shall I just buy a full new bit?

I'll try to upload a picture tomorrow

I suppose you could touch it up but I doubt it would look right.
You could either get the strip removed and re-painted, or look for a second hand one in white.
Could be wrong but I'd guess a new one would be petty expensive.

Get hold of another or have it repainted.

Replace it, look for an being broken at a scrappy or eBay

the side strips are not expensive from the dealer.
I bought the ST ones and put on my ZS (cause the ZS ones were straight and not tapered like the ST)

How do they attach??? Stuck on???

yep, stickies on the back

Better make sure it's straight

Haha watch me put it on backwards. I'm gonna have a look at getting a new one - will update when I do

apart from under the wheel arches id never use a jetwash personally...just my opinion as ive heard horror stories like that before
