After a year using Permanon Supershine on board MY Anastasia we are happy with the results on all exterior surfaces (stainless, glass and awlgrip paintwork). We have been using the Permanon as wash down soap for the last 6 months and find it reduces water marks significantly and water “beads” off when rinsing down between washes.
