If you waited until now to get tires ready for animal, its too late.
Limited you might be able to get away with.
Weekly, that would more or less depend on what chemical and how you do your program, personally i do not wipe during the week for a race at Carnesville this time of year.
Theres many preps that will fire off a tire.
Thanks, Earl, for your input. My thinking on weekly wiping for this race is the same as yours. Will work them externally at the track as necessary.
