Cheers DD... I was searching for Speedaway, not Speedway, hence the reason for getting ' no hits'.
Anyway, it seems to be used for 'soft' weeds and grasses, and some sites recommend Roundup for more persistant weeds, however, that hasnt worked for me, despite using the 'ultra' concentrate and giving numerous applications over the past 2 years....
I guess it wouldnt be as 'effective' as roundup....
