Muratic Acid on Running Gear??????
 

I almost fell down when the yard told me they get $185 per side to
sandblast, epoxy coat, and paint the running gear on a boat.......I
must have looked disoriented after leaving the office, because a guy
evidently overheard my request and approached me as I was leaving the
yard.

He said what the yard is proposing is a complete rip-off, as he's been
using muratic acid to clean props, shafts and rudders for years. He
said it restores them to pristine condition. Evidently, he sprays it
on, let's it sit for a while, and rinses it off. He said it's then
pretty much ready for epoxy and paint.

Anyone tried this before? I don't want to melt my running gear! 8)

The suggested procedure is perfectly acceptable and will not harm anything.
You may want to dilute it by 50% just to make it go further. You can also
clean the algae from the boat using the solution. Use a good respirator,
the fumes will really hurt your lungs. Skin protection with a rain suit
and a face shield is advisable also. Have done the procedure on many boats.

I don't think the boat yard is not ripping you off. Unless your running gear is
very clean to begin with.
Add up the cost of materials and the time it would take to do that job
correctly and I think you will find that price is not out of line. At least not
at yard prices.
The muratic acid will clean and etch the metal. But it will not remove any
paint that is still on the metal as the sand blasting will . And sand blasting
will leave a better "tooth" behind for the epoxy to bond to than the muratic
acid will.

just be very careful. muriatic acid is known to us chemists as
hydrochloric acid...the stuff that's in your stomach. it's one of the
strongest acids in existence.

it will still be very strong when diluted, so any runoff will attack
whatever is laying around. wear goggles and full respiratory
protection designed for acids. dont let it get on cars, other boats,
tools, etc. and dont let it run into drains. how you dispose of it may
be a problem.
