autozone usually carries paint pens by dupli-color. all you gotta do is get the paint code from the sticker on your drivers side door and match it. there are also some websites you can order off of. i'll find some links for you.
heres a long one. they offer a different array of quantities. maybe not the best prices, i dont know.
or you can just go to dupli-color.com, or search for auto touch-up paint in your search engine. if its a minor thing, you can also buy paint pens from your local dealer.
and did you know, that almost every "aftermarket" touch-up paint for torch red mustangs isnt called that? ive seen it called colorado red, and cardinal red, but never torch red. go figure.
I don't need much. I will probably check autozone. I was looking at that site helty posted and I see alot of choices. My paint is E9 but what do I get? Do I get just the pen or do I get the tricoat? It will be to fix a small chip in the paint.
I got a couple bottles from the ford parts counter $14.00 for both, appearantly when you drive 110 mph on the freeway you develop alot of chips in your paint go figure.
