We see a lot of questions online about the proper way to apply Aquapel, so we have some answers today, as well as a few tricks and tips we have learned over the years of working with this product.
To start - the surface must be clean, weather using it on a glass shower door or an auto windshield. On the car windshield we recommend a high quality glass cleaner without ammonia or high alcohol content. Clean it well, that often means a few times, making sure you remove all the grease and bugs to allow Aquapel to bond to the glass.
As the instructions say, Aquapel should be applied when the temperature is between 50 and 80 degrees. I would add to that, that in the summertime it should be applied in the shade since the sun can make surface much hotter than the surrounding temperature. Aquapel has been known to “flash off” if the windshield is too hot or if you are working in direct sunlight, which can cause streaking problems. If you apply it evenly, with long even sweeps (no scrubbing action) covering the whole windshield, the application is pretty foolproof.
But after application Aquapel must be wiped off before it dries, because if it starts to dry it will start to cloud up, and you will be spending a while buffing it off with a dry paper towel. If spilled or dripped on the paint or moldings Aquapel won’t cause any damage if wiped up immediately. And unlike Rain-X, Aquapel won’t wear off over time and cause that damaging orange and white residue that builds up around the windshield.
Aquapel can also be applied to the side and back windows of the car. When applied to side and rear windows, Aquapel lasts about a year, where as on the windshield it will last about six months. This is due to lack of windshield wiper wear and less road wear from wind and debris. Aquapel really helps with visibility through side and back windows as well aiding in snow removal. One creative idea we’ve seen is people applying Aquapel in the shape of a company logo to the back window, and in the rain you can see it quite clearly. We’ve heard of people doing a Chevy or Ford logo, even a Harley-Davidson.
If anyone out there was wondering if Aquapel needs to be removed before applying Clearplex – a windshield protection film – the answer is a resounding yes! We tried this out when we first started working with Clearplex, with catastrophic results. The Clearplex turned white and bubbled up all over the place, so Aquapel absolutely must be removed before applying Clearplex. The only way we have found to remove Aquapel is with the white pads, also available from PPG, which are actually meant to prepare the windshield for Aquapel.
Aquapel can be left on side and rear windows for tinting, since tinting film is applied to the inside of the windows and Aquapel on the outside. Aquapel will last through car washes, gas station squeegees, and ammonia cleaners, and you will have great visibility all the way around for months.
