I've just used the product on my 207, here's the thing...
Negatives;
And for me this is a massive drawback, it is very poor at taking off tar and bug marks. Very poor indeed. I would consider my car to be well looked after, it is washed properly every week to 10 days. To remove tar and bugs I use a specific product (
Autoglym Intensive Tar Remover) which I find works really well. For this reason I know that the tar and bugs have been on my car for no more than a week and there aren't many of them. Having said that, this product really struggled to remove them. In fact, I'd go as far as saying that it didn't remove them at all, I had to do it with my finger nail.
Positives;
Great shine when applied.
It rained not long after I applied and the rain was sitting up in bubbles and running off the pannels.
I also nipped over to the supermarket (about 8 mile round trip) on the wet road and was pleased to see that no dirt stick to the car.
How I will use the product in future...
1) Wash car
2) Remove tar / bugs
3) Use this product.
For me this product isn't a one stop fix, but is great to finish your car with.
