I purchased three of the Polishangel compounds and polishes in order to polish my Nissan 370Z. I must say, in my 45+ years of detailing, these are some of the easiest and effective polishing chemicals that I have ever used, and they leave a beautiful brilliant, glossy, and glass like appearance to your finish! I bought Master Compound, Master Polish II, Escalate refining, finishing, and jeweling polish, along with Master Sealant as the protective stage product. I must say, I was overwhelmed and shocked at how well these products worked on my 370Z, which has a very soft paint that gets micro scratches on it in a blink of an eye! I love my 370Z, and it's the best sports car I have ever owned. It's a weekend toy and it's garage kept year round. Even using good wash techniques to help to mitigate and reduce any self inflicted wash marring onto the paintwork, I still get micro marring on my very soft paint. I bought Polishangel after hearing it was a company in Germany that made great detailing products. I decided to give their polishes a try to see if I could bring out the best in my bright red paint. I am glad I did. They are a very easy to use compounds, polishes, and final protective sealant and I can't recommend them enough. Very easy to use for new detailers and enthusiasts looking for a very good, very effective, and easy for a new detailer or "do it yourselfer" at home. Just pair the products up with either the Polishangel pad that goes with the appropriate chemical (I recommend at least 3 of each type unless you are going to clean them as you go with either a pad cleaner, or as I do with a simple bucket of clean, warm water, with a good rinseless wash solution added at the proper dilution ratio, which will help to break down and clean all the spent compound or polish from the compound or polishing pad. I dunk them into the rinseless wash solution and then squeeze the pad repeatedly in the wash solution. I then will put the pad back onto the polisher I am utilizing and turn it on to "spin out" all of the remaining water/rinseless wash solution. Rinseless wash works perfectly to clean the pad, and once the residual water is squeezed out and then spun out at the highest speed on a polish. Any remaining rinseless wash in the pad will then act as a lubricant helping to mitigate the possibility of a dry pad inflicting marring onto the paintwork, which is counter productive, and making the refining stage all that much more difficult because you are then chasing those pesky little "tick marks" left on the paintwork. Then you can reload the pad with compound for the next panel. I only do that procedure after each panel, NOT each pass or small section. I have found that you can do an entire section first such as a door, hood, trunk, wherever, brushing out the residue between each PASS, meaning when you finish a small section or half the panel you are compounding or polishing, use an appropriate pad brush to brush out the residue. Then re-load the pad with compound and continue completing the remainder of that panel and THEN you want to remove the pad (unless you have one of the new "pad washer" devices sold from a few companies, which are pad cleaning devices that are VERY handy when it comes to polishing but they aren't a necessary product, just one that helps tremendously and can be used after EACH small section quite rapidly, then spinning out the pad, and allowing you to continue with your compounding, polishing, or refining polishing sets, basically allowing you clean the compound, or polish from the pad a lot quicker. If you are a pro-detailer, I would say the "pad washer" is a "must have" accessory because it makes cutting and polishing much faster, making the whole session go that much quicker. The washers are only about $200 max depending on who you purchase one from. It's one of those devices that whilst not "required" per se, it is truly a game changer when you are cutting and polishing a lot of vehicles. If you don't want to invest in one, and only cut and polish once a year, or once every couple years, then yes, the simple bucket of warm water containing the diluted rinseless wash will work fine for you, although it will take more time because you have to take the pad off of the polisher you are using. With the pad washer, you leave it on the polisher and it just goes so much faster and makes for a much nicer cutting and polishing experience. Once you've "cut" with the compound, you then follow with the Master Final Polish II, you can finish with one of four options that Polishangel offer, 1) "ESCALATE LOTION" which is a really nice jeweling polish, 2) "PALM BALM", which is a great choice if you are planning to apply any of Polishangel's carnauba wax offerings (paste or spray waxes or any wax). 3) "CONTOUR" pre-wax cleanser which is infused with carnauba wax flakes. 4) "INVINCIBLE PRIMER" which is a primer required for their GLASSCOAT COSMIC high durability sealant.
