I have used several products from this company in the past and had great results. I haven’t tried there Renu-it bumper gel but being a silicone product it should last longer than the oil based products like Armorall. You really want to stay away from Armorall or any oil based product for that matter. When the sun hits an oil based product it dries and looks cruddy plus over time it will actually crack the material it has been applied to. Now I’m probably going to get slammed for that comment but it’s the truth..as I have experienced. You should try and stay with water based products. All of the interior dressing products that I’ve use and that by the way Maguire’s sells are water based they will not crack or discolor over time if they are not kept wet. On that subject any leather treatment like Lexol or quality interior/dash treatment like ones from Eagle One and Maguire’s should fair better and last longer as a bumper treatment than any oil based solvent. You want to stay away from slick oily treatments the product you apply should soak into the material to not only protect it but add luster to it. If you already have discoloring my best advice is to talk with a quality detail shop in your area and get there opinion.

product Lustre All
A water-based silicone dressing that is safe for use on engines; tires; trim and interiors to provide shine and protection for black paint parts; rubber; plastic, vinyl and leather. Contains both UV blockers for maximum protection against the sun's ultra-violet rays and ozone in the atmosphere. It also contains anti-static agents to prevent unsightly dust buildup
Products like this will be just fine. There are many places online to acquire quality water/silicone based products. Two other products that I have use are Turtle Waxes Black Chrome and Rain Dance Bumper Trim both of which work just fine but they are a cover up not a cure for damage.
