Steve,
The threads that GM recommended you’ll want to take a look at are some of these.
The first are DavidK’s excellent build of the 1/72 Black Swan. The next is his build log of the Imai Santa Maria and finally his Imai Golden Hind. He has also done an Imai Spanish Galleon and Chinese Junk with threads on both of those too and you will want to follow his current Soleil Royal WIP. He did the Swan before he started using the artist oils over acrylic and then started using oils after a VERY brief tutorial on the Santa Maria. As you can see, he has mastered the technique.

Another weathering master is Rod Millard. He was the modeler who inspired me to try oil on acrylics among other tricks. His ships are amazing and well worth a look. His Catalan Ship log is here and you can see all his ships on www.modelshipgallery.com just look up his name.

And finally if you would like to check out some of my logs you are more than welcome to. Although I have to warn you, the Nina and Pinta log is really bloody long but a great cure for insomnia. I hope some of this helps and remember, everyone on the forum are more than willing to give help and advice if asked.
Steve
