Reviving an oxidized garage door, ever heard of a product called Rejuvenate?

My 20 year old brown Clopay door is pretty oxidized. So far I have scrubbed it with TSP and a scrub brush and washed it down. The results were better, but nowhere a finished product. My door has a grain to it and there is still some white marks on it. I've tried a few different cleaners, even rescrubbing a few spots, but I think at this point it is as good as it gets.

I recently purchased a product called Rejuvenate outdoor color restorer, I haven't applied it yet. Its supposed to bring the color back and add a shine for up to a year. They say that the finished product will look the same as it looks when its wet. When my door is wet, it looks new. I'd appreciate any feedback on this product it you are familiar with it.

I found another product called "Everbright" and its made for this purpose. Its a 2-step process but its expensive. The price of it is about $350 as compared to Rejuvenate that is $20!

Any feedback or suggestions welcome.

 

So, I'm sure you know that what is shown on TV may not always be the same as real life.

I looked at the SDS and it contains diethylene glycol. I was assuming it was a silicon based product (probably similar) and you've seen them on TV where old bumpers and trim magically look like new when wiped on but after a couple of car washes the coating is gone and you still have an old bumper.

If the finish on the door is well worn why not simply re-paint it? If you apply a bunch of crazy chemicals you may make that painting task difficlut.

 

A product like that might work, I've known of a few that have used it [or similar] on vinyl shutters. But Marq brings up a valid point - if the door gets repainted later, all of that product would need to be removed first in order for the new paint to adhere well.

 

That is a very good point that I hadn't thought of! I didn't even think to look and see what's in the stuff.

Per the manufacturer, after a year the shine will start to fade indicating that the product has outlived its use. I've seen silicone based products for car finishes cause a nightmare later down the road so for sure its a valid point.
