Hello Doc. This portion of the fence is difficult to reach the outside. It is high off the ground (an apartment balcony) so unable to get to the outside. Could you please suggest what product I could apply. I guess I will need to acquire a long- handled tool for the job, unless there is some sort of spray and forget’, like the 30 second one which is for use on concrete etc. Thank you.
