We use the white brass bolus QD and have been very happy with it. We chose that because it was easier on the therapists to do QD instead of QOD. Brass also doesn’t affect the PDD beyond dmax so if the physician wishes to discontinue it, we just take it off without a replan. If your MDs would still prefer 1cm QOD, I have also heard of people using those shammy-type towels, like at a car wash. They hold water really well and conform nicely.
