I had seen an ad in a magazine for an adhesive batting that is part cotton and part polyester and thought I'd look on line and see if I saw any more information or reviews.
I didn't find anything on it, but did find this very interesting article about using the spray basting.

Has anyone had a problem with yellowing that uses this method?

I will follow this thread to learn more about it, thanks

Thanks for the info on the spray basting. I have been suspicious that this might be a problem over the long run. Have also read comments about the markers that disappear or can be washed away to the effect that they will eventually cause the fabric to deteriorate even though they have been "washed out". Have personal experience with the poly batting eroding fabric on a quilt top that I completely hand embroidered some 30 years ago (I was really, really young way back then). Guess the solution is just to go back to regular basting methods and to also stay away from petroleum products!

When I lived in an area with lots of iron in the well water, the purple air-dissolve marker lines would return as rusty marks. Thanks for the heads-up.

I've seen a quilt spray basted 5 years ago and not yet quilted, no yellowing.

But I don't spray baste, at least not yet

I have spray basted twice in the past. Nothing bad happened, but I think it is too expenseive and environmentally unfriendly. I feel better when I go other routes. I still have a partial can that I am using up on small projects, but I think it will be the last one I buy. Just my personal preference.

I had this experience recently with a baby quilt. You probably don't remember but I asked for advice on removing the stains. It had sat around as a UFO for a couple months and some of the basting spray (Sullivan's, not 505) had gotten on the border strips. Nothing I did would remove the stains. It was on white fabric.

I read the article, but have some problems with it.

It's unclear to me how the writer knows that polyester batting was responsible for the seam line coming apart. There are other reasons why seam lines come apart -- such as inadequate quilting (causing seams, the weakest part of the quilt, to be subjected to stress from washing, wear, etc.), a combination of loose weave in the fabric and long stitches, etc.

I'd like to see how the research was done on the basting sprays, but there was no link to the research and no mention of where it was published. I'd especially like to know which basting sprays were tested and how long they were left in the fabric to determine that they caused yellowing or loss of fabric strength. Did they artificially age the spray with heat?

I am suspicious of the conclusions because of the statement that polyester therad is stronger than cotton. Bob at Superior Threads demonstrates that this is not necessarily so, and shows how at least some of the polyester thread sold is actually weaker than cotton thread. (Youtube has a video clip of this demo, I think; otherwise it's on the Superior Thread website).

I personally use only traditional 100% cotton batting in my quilts because I like the way it gets softer with every washing. In my experience, it really is better and longer-lasting than polyester. It's possible that poly batting wears out fabric from the inside; I just don't see the science that would justify reaching that conclusion.
