If there are great AIOs like HD Speed and Mckee's 37 360, why use 2 step anymore?

Try removing swirls/RIDS on a HARD clear coat with a DA and AIO. You might get 30%-40% correction. If you're OK with that, by all means.

My last corvette was a '03 z06 like yours. I know about hard paint. but I didn't know about DAs and polishers back then. I tried it with my hand and that didn't work lol.

I'm starting to make sense of it now a little I guess.

I suppose if you own a part time detail gig and a car with very hard clear comes in, you can expect their car isn't going to look as good as other cars you've done.

but then again, that's going to take some serious work which you might need to finish after you correct anyways.

I'm not one to chase down every scratch on a dd and thought the same as you about an AIO being the deal. I've found that at the end of the day that I'm better off doing a one step with either a dedicated polish or compound then follow up with a lsp. I like HD Speed, D156 and DG 501, all 3 have pretty good cut and clean the paint fairly well but the protection falls off fairly quickly (DG 501 is best). As far as your comment about an aio getting you to 90% I'd have to disagree with you but if money or time is short an aio is a great way to improve a fairly neglected car but a dd with hard paint your gonna struggle with an aio.

I don't have any vehicles with this much damage, but I would call that closer to 90 than anything else.

Probably because most aio products typically don't offer the correction or protection of stand alone products.

They're designed as a time saver, with the trade off being maximum potency at either end.

I use a lot of Meguiar's M66, but M205/M21 get a much better result.

I also use M66 after cutting with M105, or whatever compound combo I'm using, because it really has a nice finish to it, and holds up reasonably well. I get better longevity out of Duragloss 501 though.
 
Because you are not working on enough car to find out that AIO is not enough. AIO can handle on wash mark and light swirl, some AIO just hiding it not correct. I oftenly battle with a car over 3 years old that never even once got waxed or sealant. Oxidation, bird bomb, dog scracth mark, water spot, all these thing make all AIO in the world become junk. AIO is great for making money and time saving, but it's sure not for perfectionist.

Also, all the car I done will be coat, sealant and wax is not good enough to survived my country climate and pollutant.

PS. The defect on that Mercedes is a snack, sure AIO would work well, but even for that I still going with some fine polish, then lay down my choice of wax or sealant anyway.
 
Your current's paint condition, the level of paint correction you want to achieve, your paint's softness, etc all play a role on what product you have to use in order to achieve the level of perfection you want for your paint. A car that's damaged from routinely using the car wash is so much easier to make an improvement on as opposed to a car that only has minor swirl marks... Like you originally said, most daily drivers don't need, know or even want to achieve 100% paint correction. Heck, a 60% paint correction to them might be a big improvement already and that's all they need. I'd like to think of an AIO as a mild polish (don't exactly know the level of cut) with a wax in it. If the paint is on the soft side wherein M205 or a finishing polish would improve the paint very easily, then an AIO would work extremely well! But if you're trying to polish out a mercedes cerami-clear, then forget about using an AIO. If you're doing production detailing type of work, then an AIO might be a great product to use but if you're doing Concours type of detailing then you need to do a multi-step process. How much time do you also have? If you only have a few hours to spare, then AIO would be a good choice. But if you have more time to spend detailing your car then you might prefer a multi-step process. It all depends on various things.

So ask yourself these questions... What's the current paint condition? What level of correction do I want to achieve? How perfect do I want my paint to be? How hard is my paint and how does it respond based on my test spot? How much time do I have? An AIO is just another tool in your tool box.

An AIO is good at many things but it can't be an expert at all of them. An AIO can remove swirl marks but it can't remove them as good as a dedicated compound. An AIO can finish the paint but it won't be as good as a dedicated finishing polish. An AIO provides protection but it won't last as long as a dedicated LSP.

In paint correction, it's easy to achieve 95% paint correction. The last few % to achieve 100% flawless paint is what makes it hard.

Just my 2 cents..
 
Thanks guys. I appreciate the answers!

It probably deserves it's own thread, but I need to start looking at some correcting polishes here too. There are just so many to choose from. I come from the adam's line, and you have 2 polishes there. correcting polish and finishing polish. Nothing else to choose... Here I have several brands that all offer their own line which are several too... It's little overwhelming.
