Now that the mechanicals and the electricals are all completed it's time to start on the cosmetics. I doubt that the boat has been acid washed or polished for at least 10 years. The paint is mostly holding up. But needs attention now. I am wondering what the best acid to clean the paintwork and remove oxidisation is? I've heard hydrochloric acid damages the finish on stainless. Looking to use a soft broom, not my hands, for this job.

Re: Acid wash
Years ago we used Ospho on the hull to remove dark water stains. I was always concerned that it was doing more harm to the fiberglass than good. I didn’t think Hatteras used gel coat. I thought they were painted after they came out of the mold. The Ospho was pretty mild if you want to try that. Don’t get it on anything aluminum.

Re: Acid wash
you would be surprised at how much a little elbow grease and a simple decent wash/wax solution will accomplish.

Re: Acid wash
I should have said that the boat is being prepared / tested for clearcoating. I simply wish to know the recommended acid that will not necessarily damage any of the existing two pack paint or stainless or aluminium. It's not in the plan to hand polish the boat at this stage
