Yep. The local rabbits create a lot of havoc on bonsai out here.
Would actually spray with alcohol first. Let dry and apply the sealer. We use Top Jin and the green topped cut paste for good healing. Both have an anti fungal embedded in the product. Likely there are a couple others with similar.
BTW: It’s a good idea to include both your approximate location and USDA plant hardiness zone on your icon. To do so, double tap your icon, the Account details and scroll down to enter these data and save. This will help us advise you in the future.
Good luck!
