The product I had applied is according to my detailer:"Ceramic Pro is a nano layer of silicon and titanium dioxide which is harder and slicker than your clear coat paint. You don't need to wax your car again and it is warranted against tree sap and bird droppings etching your paint as well as no oxidizing." For my Ontario friends on here, Al Norrie is his name and he is located near Oshawa Ontario. Very reasonable prices. He coated the car paint, the car glass and the wheels with different products for each from ceramic proMy xwd is now in my friends shop. He will clean, polish and ceramic coat it. Next weekend (thu to mon) is time for Griffin.
After that all my Saab have ceramic coating.
Drove to Connecticut and back (from New Jersey) and The Mighty Thor (our '04 Arc wagon) performed flawlessly. No CEL.CEL came on last night. I noticed a couple times when the engine ran a bit wonky too. I found that not one, but two check valves had broken at the fitting. One had been "temporarily" repaired by me some time ago. I simply re-did the repair - a piece of leather and rubber cement. The other was fixed with epoxy and rebar wire. Reset the ECM and approximately 65 miles later the CEL hasn't come back on. Gotta order a box full of check valves.
Try to get in there with a mini torch and heat up the casting a bit, once it breaks free it will make a loud crack and you'll think you broke it.couldn't get the fill plug out despite use of PB blaster
