VB might be overkill for a maintenance wash, but the dwell time is just too good.

UAE?

Thought I was in r/autodetailing for a minute.

Wrong application, especially if the coating you are referring to is a professional grade ceramic or graphene. The high alkalinity is going to strip top layer of coating FOR SURE. From this picture looks like dwell time on surface is minimum 1-2 minutes. Right after wash it might seem as if your coating/hydrophobicity is not impacted but it is. You need to reapply coating maintenance product ASAP. Think of what you did as an acid peel on your face, feels good looks good, but you have to moisturize after otherwise those freshly exposed pores are gonna get jammed up with road gunk. If you’re a fan of chemie products use GSF. And for the love of god don’t get this on your glass, chemie VB down window sills will destroy weather stripping and rubber bushings that are inside the door panel.

Just use KC active foam dude, hope you diluted it right

I totally get your concern! That’s why I kept the dilution very lean at 1:30. This graphene coating is chemical resistant (rated for pH 2-12), so an occasional alkaline hit for heavy road film helps deep clean the pores. I always follow up with a dedicated sealant/topper to keep the hydrophobics topped up. Appreciate the warning about the window seals though, definitely something to be mindful of!

I do have Active Foam in my cabinet! I just find that VB works a bit faster on organic grime during winter. But you're right, for a pure maintenance wash, Active Foam or Gsf is definitely the safer 'everyday' choice. What dilution do you usually run for Active Foam?

I feel this is highlighting the panel gaps a lot more

1:10

Yeah. Those doors look rough

Me too lol

Same, and I frequent r/autodetailing far more lmao.

That's what I came here to say. That rear door straight up looks OPEN

I read this as you washing your car with terable Australian beer from Victoria.

Nah. I recently got my '25LRAWD graphine coated by a shop and there's no way in hell I would've used what you used. I would've used something basic like Meguiars gold class car wash and call it good.

But wash it again the same way and don’t top it up using anything. VB is aggressive. See how long the coating lasts. The trade off is with anything that performs that well, is at the expense of something else.

Me too! When I first saw this I thought,it’s ruined. Would like to see the finished results.

Reads like an advertisement.

I love Vb as well. These are the dilutions that I use. Disaster deatail of wheels. Iron remover then Vb at 1:3 Disaster detail of car exterior paint. Vb at 1:25. Strip wash. Vb at 1:15 Maintenance wash and moderately soiled car, Vb at 1:40-60 for both exteriors and the wheels. Here is the [video](https://youtu.be/IdzYsBi9PKk?si=hYp2Ep44fYRHyKxh)

Thats far from the fact. Forget about the coating, i use fusso coat, use Vb at 1:30-50 once in a month and that sealant lasts 8 months at least. They clearly mentioned it strips the sealants and waxes below 1:20. Anything above that is perfectly safe.

Here’s the manual: https://preview.redd.it/mq3wi69q4qeg1.jpeg?width=1284&format=pjpg&auto=webp&s=0f35598a39b1f1057d1acf586efc231ba9d9706c Max time at 1:30 is 1 minute, just one. That might also explain why your Fusso is only lasting 8 months.

VDA class B is the where you get 80-90% score. it's more like a indicator to work with than a precise prescription. 12 months claim on a fusso coat is for ideal scenarios, climates and how close we stay to the pH neutral for cleaning the car. Getting 70% of the claimed durability is a win in detailing. And getting that even after using a high alkaline pretreat on regular basis is a double win. :D I foam using ik foam pro 12, let that dwell for 2-3 minutes if there is no sun, or immediately start rinsing from where I have started to foam if there is sun, then do the contact wash with ONR.

Haha looks like my rear door, though that's more 'wonky' than anything. Shame it's on the drivers side so I have to see it every time I walk up. Apparently it's within tolerances and can't be adjusted to fit any better than it does. Annoyingly more noticeable the further away you are. Haha
