Thanks everyone. We will give the oxalic a try. We have a tub of crystals from our old GRP boat, we used it for stain removal
from the sails
and some deck
stains. I can not say it removed much, but then we were trying not to dissolve the sails
and would of diluted it substaintally.
Hopefully the metal has not melted into the paint, as it was stray dust that got in under the canvas
tarps we used to protect the deck
and should not have been a direct hit from grinding sparks.
As for how long till we sail off into the Big Blue, well our estimations on that have been so far off to date. When we bought the project
I thought it was going to be 3-4 mths to sailing, it has been 2.5 years and perhaps now it is 3mths till we can do some serious sailing. Our goal at the moment is to be able to hoist some basic sails and get up to Sydney
harbour for the NYE fireworks. It is not that far from us but we have to go out the heads, up the coast 20km and into Sydney
Harbour and we do not want to only do it on the motor
without some sails as a back up. It will be close but I think we can achieve that. Thanks for all the support, there is light at the end of the tunnel
