I use it a lot (lots of Tar around my way). I oftern one every 6 weeks rub the whole car over with it to get rid of all the TAR and other bits of crap - this leaves the paint very smooth. - Then I Polish and seal using their Polish and extra Gloss. On Tar the product works the best I have found. Their polish however leaves white resedue that drives me mad.
Thanks guys for the feedback. I think I will consider this product because I have a problem removing stubborn bonded black contaminants on the car. Not even Meguiar's Clear Coat Body Scrub will do! Maybe this ITR will dissolve the thing and leave a smooth surface...
I have tried WD40 before, quite useful on lower part of the doors, but the problem is it is very oily, making hard to clean. Because I need to remove road tar on the hood and bonnet, I don't wish to spray WD40 all over. How does Autoglym ITR smell like? What colour? Is it also oily?
