“What a great product! Applied directly to fibreglass lorry roof that was prepared with a quick wash and sand! Used a decent 7” Brush and actually applied it at under the recommended temperature (due to the good old British winter) and ended up running out of light before completing the full roof… and then the heavens opened for the following 4 days!! So, I wasn’t too sure what I was going to go back to once the rain had cleared! It seemed that the paint had settled enough for the rain to not actually affect it at all! And then carried on the job and have had absolutely no issues! Goes on really well, leaving me feeling very confident in its abilities and two 5L tins covered a 18sqm roof, with a fairly thick layer and do have perhaps a 1/4 of a tin left! Would recommend so far and the grey is quite a light colour but still looks good!”
