I have been researching different surface finishes. I have read about it before and incorporate a rough finish in my porting of cylinder heads in the intake runners.
Boat hull or Pontoon finishes I have not experimented with..I just kept them clean and went fishing.
But I have a 20 foot Pontoon with brown buildup on the toons where the water line is at. and rough mineral buildup that I need to remove.
Acids do not remove it and vinegar with scotch bright removes it as does plain water and scotch bright or 600 wet sand and plain water.
SO I will be removing it with plain water as I do not like the thought of acids of any kind on my aluminum.
I will start with 600 wet sand and finish with 1500 then some buffing wheel or terry cloth and hand buff and slick it up. That was the thought anyway.
Got me thinking of boundary layer and many times a hull will be faster with 600 grit.
But rough surface may allow contaminates to cling or build up on the pontoons after a few trips.. So polish or not to polish.
Is it so slow it will not make any difference is boat speed anyway?
What do you guys do?
