Help needed, every time we wash our Motorhome then we wax it, the dreaded black streaks are there as soon as it rains we have tried to wax all black rubber parts that are showing doesn't work has anyone got the answer please. Thanks
Hi, think you will find streaks are caused by the sealants and not the seals. I use a product called showroom shine to wax my van then these black streaks clean away easily afterwards.
