After reading a few reviews for soft top cleaner and proofer I thought I would give this a try. Now my roof wasn't very dirty but a few marks on it. The cleaner foams up nicely but do make sure the roof is wet, add some more water if needed. My roof was a bit dry and I ended up using too much cleaner to make it foam and it took an age to rinse it out! I used half a bottle on a large roof and it was way too much!
Once dried out the roof looked nice and clean. Then to use the proofer, went on easily and brushed it in to make sure I had even covered. Dried fine and any overspray came off easily with some QD, gave it 24h to dry out and give it a once over with a clean cloth as instructed. Again a nice even finish. A few days later it rained and the beading on the roof is amazing! Can't comment on longevity yet but first impressions are good. Brushes are nice too ;)
