Wow that sucks !
I had a 71 HG Monaro and the servo down the road had a very high presure washer and I took half the black stripes from the bottom of the guards. But that was 30 something years ago
Look on the bright side ! Now you can get a decent paint job on them
I am planning on putting the vinyl that sign writers use on some of my lower panels and flares as the paint work is shit house and cops a pasting. At least the vinyl will help protect it longer
Sorry about the paint But I had the paint peel off just above the windscreen My d40 is a 2007 model Nissan fix it I have never done any four wheel driving or used a presure washer It was a bad paint job It started to peel off after 31/2 years Pete
