I have searched the internet but no real joy, basically I have noticed that my 2 year old Tohatsu paintwork on the lower leg is suffering what looks like salt/water marks on the paintwork. Please see the pictures attached. I donít think itís a problem with the clear coat/lacquer because my previous Yamaha outboard had exactly the same problem, which only got worse over time!
My rib is in Mallorca, the water out there (the Mediterranean) is very salty so I think I always assumed it was due to that, a reaction or something. On average my rib is in the water for about a week at a time and I wash my rib down extremely well when I take it out of the water and polish/wax the engine before going into storage. I try my best to wipe it down with a spray bottle of water and micro fibre cloth after every use whilst it is on the water/my mooring.
What can I do to remove these marks? The best I could find via Google was to use an acidic toilet cleaner sparingly, and lots of water and then polish/wax straight after. Is this a good idea? What about using wet and dry sand paper? Like the highest grade available and sand it down with water and then polish and wax it after? I guess this could affect the clear coat/lacquer though and would be the last option! Though I know this would definitely work as you can in fact scratch the marks off with your finger nail! Surely this is a common problem and there are products out there for this?!
Thanks for your help,
