303 graphene longevity issue

Gee, I received it as a prize and haven't used it yet. Now I'm hesitant to. Maybe I ought to reserve it for wheels.

No reason not to try it....maybe your results will be better/different than mine. I'm one of the few people who dislike P&S Brake Buster, too....so maybe I just don't know how to use these products.....I'm always willing to admit it might just be user error.

I’m not sure what problem you guys are having with the 3 03. I’m going on 5 months and it’s still beading and glossing well, yes my car is garaged but it’s driven every day/1500 Mi a month. I also run it through a touchless car wash about every two weeks and that has not diminished the 303.I do top it off with some Carpro elixir occasionally but the 303 is my go to for a sealant right now, I’ll use it every six months or so. Compared to some of the stuff out there, it’s also cheap.

The only downside I see with this product is if you don’t wash your microfiber buff off towel right away, it will turn that black. I also put it on with a black microfiber brick.

The videos ScottHD has with this product doesn't look that impressive or even that durable. But its a spray so who cares. Just use it more often.

What you consider still glossy and beading may not be what others would consider the same. I’d be interested in pictures of 5 month old 303 beads if you can post...

Could be that the touchless car wash isn't just spraying soap on your car. The car wash wants people's cars to look good when they leave so there might be some type of wax product added to the cleaning process.

I have no experience with 303 Graphene, but this comment caught my eye. The results you're seeing could be due to the usage of Elixr. I found Elixr to be surprisingly durable for being categorized as a QD spray. When used on bare paint (long story, never wanted it to be an LSP) I found it provide great LSP-like properties for nearly a month!

I thought that comment might bring that type of response. No, I got at least four months out of the 303 before I ever started the elixir and it looked good…… if I get 4 to 5 months out of a product like 303 which is so easy to put on and get off, that’s enough protection and durability for me. I only used the elixir once and it was about two weeks ago. It definitely did amp up the gloss.

Nope, I always choose the “express” selection which is nothing but a soap and water rinse. They were servicing the facility several months ago and I stopped and talked to the guy working on it and he confirmed that express was just a quick soap and rinse, no Protectants or waxes.

I've applied this product to a number of cars but most of them I've never seen again. It is on my neighbor's 2019 Toyota RAV4 Hybrid. It's parked under a carport most of the time.

I'll ask the owner when he's planning on washing it again and then ask him to pay attention to how the finish looks on the RAV4
