Tar spots? - Malcolm
Where does the tar that appears on the bottoms of doors come from?
My car is only 2 months and I have not to my knowlege driven on any recently resurfaced roads nor has the weather been hot enough to melt the surface.
Does it come from vehicle exhausts?
Answers please,
Malcolm.

I'm fairly sure its from the road surface. Remove it with white spirit, polishing the areas afterwards. Mud flaps will help to reduce the problem.

I have found that a good polish like Mer will also remove tar spots effectively,
with no danger of damaging the paint.

I'd be wary of polishing tar off, as it takes a while and the debris on the cloth will scratch the paint. I think it's better to dissolve it first (and white spirit won't harm the paintwork) and then repolish. This was the concensus of the previous thread on this topic.

I live in the Northumbrian countryside so I know what "cow poop" looks like!
My car is silver and it is definitely tar spots.
Not to worry, no big deal, just curious how they get there in cold weather. It's easily cleaned off as I myself explained in the previous thread.

Malcolm,

I live near Bishop Auckland , there is no Cow bobbar any more as they have slaughtered the majority of the Cattle.!

Perhaps the spots could be a by product of the many Pyres in the area

Are you absolutely sure it's tar? Round my way (S Glos, prime F&M country) it doesn't take much to get specks of cow s**t on the door bottoms and cills. On a dark coloured car you'd think it was tar. If it is poop, try a warm soapy water soak.
