I seem to keep crashing other peoples threads so I thought I would start my own.
 
I bought this 12 in the summer and sailed it up to about the end of Sept. I then brought her home where she sat in my garage for a month or so.
I then talked my wife and son(11) into helping me turn her over for a coat of paint.
 
I had read on here (i think) that a random orbital sander would be the best bit of kit for the job.
I planned to just rough her up a bit and give a fresh coat of paint. There had been a couple of repairs that had been varnished to seal.
 
After half an hour she looked like this .
 
 
This is point where I decieded to take the whole lot off.
 
 
That was about 2 hours of sanding.
 
More tofollow if your interested. ?

Looking good Paul. I always like a nice 'project blog'.

Looks like your bike will need a bit of a clean and oil to get rid of the paint dust!

And onto the other side.
 
 
 
A couple of previous repairs looked sound.
 
 
 
I had to use some paint stripper to get into the corners.
 
 
Then 3 coats or Eposeal 300 was appiled.
 
 
 
 
Just got to wait 7 days for the epoxy to cure.

That is such a nice hull shape.

What condition is the inside in?

Really? Appreciate your garage may not be quite 15°C, but if it is, then min time before sanding is 28hrs (according to the data sheet). The time does increase exponentially with decreasing temp though.

I left the keels on because no one gave me a good enough reason to remove them. I did plane a few milimeters off them.

The Data Sheet for the Eposeal says "if the primer coats of eposeal are to be overcoated with a solvent free epoxy system, then the eposeal must be left for 7-10 days to ensure it is thoroughly cured"
Yes it can be sanded a lot ealier.
 
Maybe I have it wrong ?

i think old boats with history dont matter if they have a few battlescars it shows they have had interesting and eventful lives. Those repairs are a little rustic though.
