You can easily prevent wax from getting in between the scion and the stock by using a paper or cellophane.

These grafts were tied with tape. I'm sure that this oil would penetrate anything which was not absolutely air tight.
Winter Injury of Filberts at Geneva 1933-34[A]
By G. L. Slate
New York Experiment Station, Geneva, N. Y.
Last year I reported to you the winter injury to the Geneva filbert collection resulting from a very mild winter. This year I am reporting the damage resulting from the coldest winter on record in western New York. Varieties that have withstood both winters may be considered sufficiently hardy for anything western New York and regions with a similar climate have to offer in climate.
A brief summary of the winter and its effects on other fruit plants in the vicinity of Geneva will serve as a background for the data on filberts. The first severe cold occurred on December 29 when the temperature dropped to -21° F. This equalled the previous low record established in February, 1896. On February 9 the minimum temperature recorded was -31° F. or ten degrees lower than anything previously recorded in the history of the Station. The minimum on February 8 was -16° F. and on February 10, -18° F.
Fruit trees suffered severe injury from these extreme temperatures. Nearly all the older Baldwin apple trees in the vicinity were killed or so severely injured as to be of no further value for fruit production. Peach fruit buds were all killed and many of the trees succumbed, even in well cared for orchards. Very few sweet cherry buds survived, and many trees were injured or killed. Delaware, Catawba and Niagara grapes were also killed to the ground or lost most of their buds. Japanese plums failed to bloom, and the trees were severely injured. Nearly all climbing roses were killed to the ground. Even the native elderberry, Sambucus canadensis, was killed back in many cases. Such was the winter experienced by the filberts.
