Thanks for the tips. Glad to hear the Mother's kit is OK. I can be impulsive with stuff like this, so I was regretting not looking into it further.
I worry about not getting the Iron-x completely rinsed from all of the nooks and crannies of the car, namely the edges where the doors or hood meet the car. Can it do damage if it dries to the paint?
I have been jonesin' to get the PC 7424XP for a few days now and will likely pull the trigger on it soon . So yes, I'm 99% sure I'll be attacking this with a DA! I haven't pulled the trigger yet as I'm still studying which pads, polish, etc I need to get with it.
The car is black - no idea what polish I should get or if I need to get it. The Mother's kit came with their 'Reflections Car Wax', 'Spray Wax', and 'Top Coat'. I'd love to save some $ and be able to use these, but willing to scrap them if there are better options out there. I don't want to cut corners because I was trying to save a few bucks.
Well I ironX cars quite a bit. As long as you give a thorough rinse, it should be ok. I havent had trouble with it yet. But be careful if youre doing it outside, if the sun dries it on the paint, you may be in trouble.
I can tell you right now, get the Griots Garage 3 DA. It has more power than the PC and is overall a nicer machine.
Now your audi has a ceramiclear clear coat. In the production world, there are three different types of clear coats you will come across
Carbon - Rarest and most expensive, only the ZR1 has it to my knowledge. Debatably the hardest, but not in my experience.
Ceramic - Most new cars are switching over: all Mercs, audis, and new fords got it. This is an extremely hard clear coat and takes a lot of muscle to get swirls out
Acrylic - The most common and out of the three the softest clear coats. Cars like Toyotas, dodge, etc. have them.
Now for the ceramic clear coats, I would hands down go with the Menzerna Polishing line. I have seen quite a few people complain that the Megs and Optimum lines dont have enough cut to pull swirls out.
For your car I would:
PF2500 - on a white or an orange pad
followed by
SF4500 - on a gold jeweling or a red finishing pad
If you have super deep swirls, try IS1500 or FG400, followed by SF4500.
SF4500 is not a glaze or a filler, it is a nano polish, and out of all of the polishes on the market, makes the glossiest finish (91 Gloss Units @ 60 degrees).
For waxes, the mothers ones are made for all colours, fairly generic. You will find they might not last as long as other waxes out here and their water repellency is not going to be nearly as good as others.
How much are you willing to spend on a wax? Under $100 for a black car, you should go with CG Black Wax, or Pinnacle Souveran Paste Wax. Over $100, I will be honest with you, skip everything you see on the site here, and go straight with Swissvax Onyx or Shield. Swissvax hands down make the best waxes in the world and its the only premium waxes I will use, if you want more info on them, PM me!
As far as cutting corners, I have tried in the past, it is cheaper to get the best now, and skip buying cheap stuff, and then realizing you need high quality stuff.
