When people ask me about French polish and I tell them it is possible to completely French polish a guitar in a fraction of the time that it traditionally takes to apply a French polished shellac finish, they are amazed! In fact, My students and I finish a guitar together in my six day classes in 6-8 hours working together on the instrument. 
I have an online course that shows exactly how I do it. Here is what someone had to say about the course. 

"Just wanted to thank you for your FP video!   I did my back and one side this weekend (in between honey-do's) and am really pleased with the results so far - and, I find the whole process really satisfying.  I'm a long way from done but wanted to add to the feedback you're getting for this video, it's really great."Clay

Judging by the result shown in the picture below, I think Clay did an excellent job with little to no experience working with shellac. You can also get these results by following the instructions in my Online French Polish Course. 

Here is another quote from a student.
"I can not say enough about Robbie O'Brien's French polishing technique and his on line class. I have successfully learned a few different methods including Milburn's. Robbie's is the clearest most straight forward, and repeatable method I have tried. For me it was worth the cost of the course, I have use this technique on most of my classical guitars." John
