MS can't be that bad... lot's of the Vaux boys use it.
Just because no Punto geeks here in the UK have used it dosn't mean it can't do the job.
It's like anything... suck it and see.
Hell I asked on here about KMS once, because I know alot of the Cit/Pug boys use it on TB & SC cars... but no one battered an eye lid.
