Tyre marker pens!

 Hi guys, has anyone ever used a tyre marker pen to highlight the tyre brand in white / silver etc, is it any good, does it last & whats the best brand to buy, are there any reasons why I should just forget the idea   . I've seen some tyres done &    but I don't want to have to be continually maintaining it,    I'd appreciate your thoughts  

I did years ago but I have no idea of make now, worked well and was only occasionally touched up. It doesn't matter with the writing if it stays properly white or not as it is so little done, not like a whole tyre.

I did tyres on a bike a while ago lasted well did need a touch up every now and then but on the whole I was pleased with the result. sure I still have what I used in the garage will have a root through there and if I find it will let u know what brand it was

Did it on a car i had in the late seventies,  and it worked very well then, minimal touch ups.   I am guessing it is still just as good if not better these days.   good idea,  i might go looking for some myself.
