3D ONE for failed sandwich bag test?

[ABSAV]

Situation: 1 year old Prius garaged kept car. After road film wash, foam wash, contact wash, then using a fine clay bar with ONR as a clay lube the finish felt smooth to the touch. Using the sandwich bag test for check on final on smoothest - it failed (feeling rough). Do I go straight to my 3D POXY for my LSP or first use 3D ONE with a white Buff & Shine pad then hit it with 3D PROXY for my LSP? Any info that can be provided will greatly be appreciated. Thank you always for your time and experience, ABSAV

If it’s failing the baggie test, then use a clay that is more aggressive than the one you used. That may also add more marring to the paint so you could end up having to polish anyways.

What would add more marring the clay bar or 3D one?

I did try a test spot using both products, which did do the job, but would like to keep as much as possible the thickness of the clearcoat. I am looking for the least amount of invasiveness.

If it is a daily driver, I wouldn't get too hung up over the baggie test. Claying is a essential part of the decontamination process and needs to be done, but sometimes I think people pursue perfection in a daily driver that isn't practical or achievable. Unless what you're feeling is really rough and over large portions of the car, I'd probably press on with the polishing.

Thanks for the reply. It's a daily driver. are you saying go ahead with the 3D ONE then go with the PROXY for the LSP? With what pads? And when all finished not worry about the bag test?

For what it's worth - I've clayed a lot of cars in my life and I would have to say that I never really see paint become 100% perfect.

After a thorough claying it will be MUCH better but it's pretty hard to make the Baggie Test 100% on all cars. One thing for sure, claying will make a huge difference. Instead of focusing on the smidgen of bumps you still feel - focus on the millions of bumps that have been removed.

For a daily driver - I would push through. Machine polishing simply because you're removing some paint will act to remove more of what claying missed.

Thanks for replying Mike. I am going through with a med/fine pad using 3D one and finish up with a fine white finish pad puting down POXY for my LSP. Great info experience as always.

If your Prius is like most other Toyota's I've worked on, the paint will be really soft and easy to correct. I'm not sure which pads you are using, but I can correct my wife's Highlander or my father-in-laws Tacoma using nothing but a white Lake Country ThinPro or Flat pad and a finishing polish in one step. When I still used sealants I'd clay, polish, and then go right to the LSP.

Thanks Desertnate, Thanks for the heads up. I am using the Buff & Shine White pad for the LSP and a B & S dark blue (med/fine) with the 3D ONE
