I have been told by people successful with the Copper Coat that you must go over it at least annually with something like a scratch pad, it must be roughed up to release the copper. This can easily be done in the water
. Also, proper application is imperative. Don't let a yard do short cuts. Spraying it on is probably a bad idea because most of the copper will be left in the spraying assembly, roll it on. I intend to put it on the bottom of my boat
in about 3 weeks. Four coats rolled on all in one day, with about 45 minutes of drying between coats. Absolutely no water on the hull
for 2-3 days- including protecting it from dew dripping down onto it. Then, another 4 coats in one day, let it dry for a couple of days. Move the boat on the stands, and do the same thing with the remaining blank spots. So, I am looking at about 10 days on the hard
to do the job. You must first sand off all the old paint- to the barrier coat. Prep is extremely important. Rough it up gently before splashing.
