How do i remove smoothrite?

[Bigjoe]

Afternoon all,
whats the best way to remove smoothrite from car paintwork, ive somehow managed to get some on my paintwork (god only knows how) im not sure about hammerite thinners not damaging the paint, has anyone got any ideas?

I might try some hammerite thinners on a non obvious place

if your using hammerite thinners use it gently,don't rub to hard,its strong stuff.

if its original car paintwork try some cellulose thinners as long as you dont go completly mad it should be ok

If it hasn't been on there too long, how about a clay bar + lube?
