JoeyO wroteHonestly, even when new you'd be surprised at how much stuff can collect and present on a cars paint-job. Seems like you are a careful washer and thats great, but it isnt just noticeable swirls that steal away from a cars potential to shine.If my vehicle is only three months old, would I need to polish the entire car before applying a ceramic coating? So far my vehicle doesn’t have any swirl marks or scratches. I’ve been very careful in hand washing it to prevent those things.
Environmental contaminants from transit, sitting at dealer, day to day road gunk, brake dust, you name it. Most of this isnt easy to see or see at all but its there.
A paint correction and prep(polish & clay bar) is always best but it isnt mandatory. The polish will also remove any hard to see marring, swirls, etc. that you cant easily see. At the very least you should do a decon wash(soap specific for this purpose) to remove some of those mentioned contaminants.
Then, apply your coating of choice. Just decide how far you want to go.

sprmario wroteThey have Si "agents" in the formula bit no, they are not the same as say Car Pro CQuartz,, Gyeon Mohrs, etc. However, they DO work quite well for what you pay and how easy most are to apply. I use the T-Wax Hybrid for our daily drivers and have no issues with it.None of these sprays in the video above are true ceramic coatings. They are spray on wipe off ceramic products that are usually rated at around 6 mos. I’ve used turtle wax ceramic spray and it requires me to redo it after about 6 mos because it starts to fail. Still it is very cheap so it is fine. You can also extend the life with their ceramic detailer.
