About time. I'm just surprised it took so long to have a meaningful discussion on this subject. I have raced many times in glue races and only a few times in spray glue races. It's spray glue for me. Mainly because I'm old and can't get around like I use to. Those 3 min breaks between heats allow me to sit down and relax my sore knees instead of struggling to glue my lane.
One more benefit to spray glue racing, no more giant hub tires at $20+ each. I sold all I had a few months back. Will be racing with .500 hub tires from now on.
I've done so much with so little for so long it seems like I can do anything with nothing at all.
