If it's your first time spray basting, I recommend using 505. Just be careful not to spray too heavily; it doesn't take much. Occasionally I see posts about problems with other brands; never with 505. I don't think any spray basting brand causes a problem with machines. Worst problem would be using an off-brand that is too old and spraying too heavily, in which case you might get a sticky needle that needs to be wiped off with alcohol periodically as you quilt. I do agree that it's best to let the basting spray dry thoroughly, as in overnight, before you start quilting. To speed drying, you can also iron your quilt sandwich. It compresses the batting, which can help a quilt fit under the arm of your machine, but the batting springs back to original height when the quilt is washed.
