When I traded our 5 year old Montana in on our 2010, the toppers were in good shape, some staining. My advice is to keep them clean, without stressing the material. Keeping the underside clean is difficult. Too much scrubbing will certainly stress the material. Do not put any supports under the topper which puts pressure on the awning, as it will cause the topper to permanently stretch and weaken the material. And always try to give the toppers time to dry out before closing. I have never tried any UAV protection products and have not had to do eternabond repairs.
