Oh Cool! I'm betting you are going to like using oils, at least I hope so after I've been raving about them. Be sure to keep an old rag or something to wipe your brushes while painting. There is little need to be cleaning the brushes while painting, just wiping it off on the rag is usually all that is needed. Remember to put very little blobs of paint on your pallet. A little Oil paint goes a lot further than acrylic, and you don't want to waste considering the cost.
As for Liquid White...I've used it.....but not much. I still have the original bottle I bought Jan. 2015. I find that the Liquid white (I'm using Wilson Bickford brand instead of Bob Ross) prolongs the drying time to the point of frustration...sometimes taking 4 or 5 days before I can add the next layer. Instead what I do is take the Walnut Alkyd Medium and mix it with Titanium White making it very loose.. the consistency of liquid white and use that. Then when you paint the sky to blend it works as well as the liquid white but your sky will dry in a day so you can add trees without making mud. I believe that liquid white is Lindseed Oil mixed with Titanium white. I would suggest since you have the Liquid White you add a few drops of the Alkyd Medium to speed up the drying.
Another technique that I really like to do is to first seal the whole canvas with a very light coat of the Alkyd Medium. I spread it on with a brush then wipe it with a paper towel so only a light coating is on the canvas. This helps a lot with the blending and it also keeps the canvas from sucking up the paint.
