I love 505 the best of any spray baste. It doesn't have an odor and washes out easy. The cost is the only thing I don't like about it.
I like June Taylor's spray baste. I found the large can at Michael's and was able to get it for $7.13, that is after a 50% coupon. I have basted 3 good sized quilts with one can. It does seem to have a light odor but it didn't bother me.
I extremely dislike the Sullivan brand. It goes far but the can I used had a horrible odor. It didn't completely wash out either. I had to air the quilt for several days..
