Plastic Bumpers

[Gunzz]

Well today I have had it with the black bumpers turning a greyish white haze. I have bought numerous products but everything has only been a cover up. I know it's my fault as I take my truck through an automatic car wash between once and twice a week and even though I don't opt for the wax wash which is the addition of silicone in the water, I end up with the silicone anyway building up on the bumpers. This turns them greyish white.

I have spent countless hours searching forums and auto detailing groups, and have tried many of the members suggestions, however it would only mask the problem for a week or two, and then here returns the hazy bumpers.

Well I think today I came up with the answer, well at least I am hoping. After reading so much that alot of the haze was indeed what I thought, a buildup of silicone wax I decided to give something a try. I recently ordered a product called wax blaster, but it has not been delivered yet and I was getting impatient, so I decided to try Goo Gone. I says don't use on rubber however it seemed safe on plastic so I gave it a try.

With a scrub brush, I sprayed a portion of the bumper, let the product sit for a minute, then scrubbed it in a circular motion with the scrub brush. After letting that sit a few minutes I wiped it with a dry clean towel and what came off was a mess. A load of waxy buildup came off immediately allowing clean looking BLACK bumper to show through. I then used a wet towel and completely rinsed the area.

Now I know the bumper has looked good after the use of other products, I was a little reluctant to believe that the Goo Gone had worked, but I do know one thing. What came off on the towel was a big messy buildup of silicone wax and I think the Goo Gone has worked in removing the wax. At least I am hoping so. I will give it a couple days and then put a good protectant on after I see how it looks, but I want to wait to see it's real outcome after a few days of expected rain.

I'll let everyone know.

Keep us posted! Very interesting. I have refrained from "dressing" my bumpers just for that reason. Any silicone product will slowly hurt the surface its put on. Silicone is used for gloss and shine. Be careful what you put on your plastic after your experiment. I use 303 protectant on my interior plastic and it looks and works great. has UV protectant with no silicone and leaves a nice low gloss shine. Satin looking. I have used the 303 on my last H2's black plastic exterior trim but it wouldnt last past the first rain. Silicone products will last in the weather but I feel aren't worth the aggrevation after seeing what they do to the plastic over time. (the white hazing your talking about.)

There was a thread on this a while back and I'll repeat what I said then. The only product to use on black plastic or rubber is Black Again. I've used it for over 10 years on my Concours cars. I run my Hummer through car washes twice a week, and the product lasts for 3 months before needing another application. Here's the linkif anyone's interested.

I would agree 100% that for black vinyl and rubber there is no better product than Black Again. I've used it on several of my cars for years and use it on the Hummer. I get it at O'Rileys and the newer cans say Professional Detailers Formula on the top of the can. If you've ever been to a Barret Jackson auction, you'll find one of the last things they rub on the tires and any vinyl before they put it up on the stage is Black Again.

I have never used Black Again but am Willing to try it. I use only Prpfessional detailing products with only top qaulity ingrediants. Is Black Again a restorer? or used for general maintenance? Does it inhibit sun fade and the greyish turning process? I would assume that if it lasts for months it must be full of silicones and oils. Which is ok if you use the product consistantly and forever.
