They're smaller than I thought they'd be: What's that? You don't know what a Mum-Mum is? For reference: Sent via Tapatalk.
I have yet to scratch my blue paint, but I do have a scratch on the wheel that I'm not ready to touch up yet. Maybe I'll give it a try. How long do these things last if you touch a tiny spot? Will they "keep" if you haven't used them for a while? Those are my questions. Sent via Tapatalk.
From my experience with paint pens in the past, I had touched up spots on my Audi still good after 10 years. The pens keep a long time - 5 years maybe. Keep them on their sides, cap on tight, in a ziplock. Shake vigorously before using. The tips, not so much. Maybe get a few uses out of a tip before you need a new one.
Have one of the service guys order one for you and pick it up. That's what I did at the Portland service center when I had my second charger installed.
It is, though I find that the shipping amount is the same whether you order one item or five. I tend to wait and buy a few things at once - a couple paint pens and a few mobile charger adapters this time around. Still just $9 for them all.
