tenyawph Turbocharged January 25, 2017 Share January 25, 2017 Of course. Polishing will allow you to remove fine scratches easily. However, I have a question. What kind of stains do you have on the PPS? Are they water marks or bird droppings? If they are bird droppings, then with PPS on your car's paintwork, you should have no problem wiping it off. However, water marks are difficult to remove, as they might have penetrated quite deeply. You might have to sand down the PPS coating and even worse, the paintwork itself. The good news is that in bright sunlight, you should not be able to see the water marks easily, so sometimes, it is better to leave them alone.

The PPS comes with warranty right? So if the stains cannot be removed and you are still within warranty, then go back to the detailer to remove the stains for you.

The one i went to covers all stains leh.. be it water or bird poo or mud/tar stains. Which detailer is yours? From what I understand, most detailers require you to come back for maintenance ie they re-apply another coat every 6mths to 1 year at least. 7 Link to post Share on other sites More sharing options...

Taking this opportunity to do run a quick one on water spots and coatings When the the rain water evaporates, it leaves behind concentrated minerals which forms the whitish rings on PPS coated or PPS un-coated surface. A good PPS will be able to resist the adhesion of these minerals with weekly wash with shampoo. In event if the minerals had made its way to the coating, young minerals can be broken down with acid base water spots removers without affecting the coating or paint if its used as directed. Check with your detailer on what can be done when you start to notice water spots and not wait till as and when you feel like. The sooner it is, the better chance of resolving this. On un-coated PPS surface, chances of removing water spots will be very slim as they had gone into the paint which we call it "etching". Try this at home. Get some rain water. Spilt them into 20 parts. Evaporate part in the same non stick pot. Try to wash off with shampoo after the last cycle and see if the rough remains can be washed off. Out of desperation, we use rough washing wool to try to scrape it off. The water spots most likely will be gone but non stick pot gets scratches and it no longer becomes a non stick pot. Same thing, try it on a normal pot and see if the remains can be removed with rough washing wool. There is limitations to every thing. A Good PPS, will be able to delay damages to the clear coat which can be repaired easily by removing the affected coatings and reapply new ones to protect the paint again. Usually lower end coatings will not be able to take the concentrated remains and damage the coating and goes into the paint directly. When that happens, its considered irreparable under polishing. Small concave will still be seen under heavy compounding under certain angle. Wet sanding may help to reduce the concave further. But it will take a lot of time, effort, skill, related gauges and equipment would be needed to make sure the paint has not been over sanded and is able to have some balances for future polishing. Most detailing company are not willing to go into wet sanding. Generally, to prevent water spots from happening, its good to keep the car dry as and when we can. Maintain it the way your detailer recommended. Different companies offers different types of warranties. Some warranty on gloss, verbals, manufacturer, workmanship etc. Most will not warrant on water spots for pps without any "fixed" commitments like compulsory purchase of XXX numbers of car washes within certain amount of time. Coatings are hydrophobic / super hydrophobic "beading". A point to note on Good PPS, it should resist contaminants to stick on clean surface and be able to carry away when in motion. If your detailer is garang to warranty on water spots without any "fixed packages to purchase" save your money and time. Stop washing your car as of today. Snowball the water spots for 1 month (most likely its impossible to be removed with chemicals) and get them to do it FREE for you again under warranty claim. Even if this does exist, have you questioned the detailer how much paint thickness is left after the 2nd warranty claim?
