No rust is showing. I already got 2 different touch-up kits the paint will not adhere though it needs filling & priming first as 1mm deep. I got a pro booked or tomorrow now it's only a tiny area but bothers me a lot so willing to spend £££ for a pro to make it go away & carefully blend the triple layer!Touch up pens? (Not sure) we used a touch-up pen on my car where rust was showing , worked well

nice car back on the drive so its back to 2bm and staying away from the hand car washes, no doubt my daily will also be thankful
