@Barkslip, Thanks a bunch for much needed explanation of the finer points above. Kindly keep on educating, some of us less experienced grafters can take advantage.
With that said, what’s your take on using Aluminum foil or Lunch bag to cover the grafts and prevent from Sun ?
May be I am splitting hairs but last few grafts I have used paraffin film, then covered with Lunch bag and then final cover with Aluminum. Some grafts I have used just Paraffin and Aluminum cover and plan to do few more with nomparafilm and just aluminum cover. Plan to report at the end of grafting season.

I think it’s personal preference and what you were taught. Aluminum foil will keep a scion as well as a union (your working carpentry) from overheating. So, mid-80’s and into the nineties that might be a wise decision to cover scions with foil.
If you have parafilm and electrical tape, you can do anything from 3/16’s to 4" diameter trunks. I’d like to have some sealant on a 4" but I can use electrical tape and parafilm and generate callus.
best regards,

Ok, I had not considered the direct sun on the grafts. I have been working with potted seedlings, and leaving them in at least partial shade for a while. I suppose I have a tendency to not think much outside of what I have experienced. A trait too common in people I have noticed, looked like fell victim to the problem, also.
Thanks for the input.

Do you think 2 year old scion wood that has been wrapped in plastic wrap and refrigerated the entire time would be viable?
I know from another guy that I really like whom has a lot of experience. He’s grafted wood collected at Fall, grafted the following June with tremendous or very good success.
The typical amount of time scionwood is very “good” is 3-months. Holding onto 6-months total. That’s the general truth of it.

Odds not good, but you can’t be sure if you don’t try.

I’ve successfully grafted and rooted 18 month old fig cuttings, so it seems possible that 2-year-old scion wood could be viable, but probably not. Some species store better than others. Fig is very easy to store, whereas cherimoya is not, for example.
