I haven't had good luck with the stripe application gel... Windex window cleaner is another product some use. I now offer a stripe application fluid that dries quickly and yet allows a good repositioning window. It will also dry through the vinyl for trapped bubbles and leaves no residue. Also it's pre-packaged so it's not going to have any contaminates or trash in it that you might get mixing soapy water yourself. I've read of people putting stripes on dry, but this method allows no room for error in positioning and any bubbles will be trapped air that can only be removed by pin pricks. this method allows no room for error in positioning and any bubbles will be trapped air that can only be removed by pin pricks.
1. Do a dry test fit first, marking the locations with small pieces of masking tape. Verify that both side stripes are the same distance from the rear edge of the quarter so the deck lid stripe will be parallel to the back edge.
2. On the side stripe sections center the stripe front to rear relative to the side marker hole. Also note the up/down dimension to allow the correct amount of material into the trunk jamb; also the correct positioning of any R/T or Bee graphics as it applies.
3. Clean the area to be striped first with a water-based cleaner. Then follow with wax & grease remover. Last, wipe it with a tack rag just as if you were going to paint it. This ensures that you won't trap any dirt specks under the stripe.
4. Peel off the backing material and apply the stripe application solution to both the stripe & car one section at a time. Be careful not to touch the backing or get any dirt on it. You can start a corner, wet it with solution so your fingers don't stick to the adhesive. Also be sure your hands are clean!
5. Carefully position the stripe sections. I like to place all 3 pieces before pulling the carrier sheet. This gives you the option of repositioning for alignment if neccesary.
6. Squeegee the stripe thoroughly with the carrier sheet in place. Once the carrier sheet is pulled, squeegeeing can scratch the vinyl.
7. Allow plenty of time before pulling the carrier sheet. Too soon and you risk pulling up the stripe and trapping air under it.
8. Once you've pulled all the carrier sheets, rewet the edges where the stripe bends into the jamb or around the deck lid. Use a heat gun to warm the flap slightly as you work it down. It will take a little time to dry the solution, but it prevents causing a wrinkle from it sticking too soon as you fold it over.
9. Most important!... only use the heat gun for the edges mentioned in step 8... any remaining bubbles are trapped solution and will come out on their own. It can take anything from a couple days to a couple months depending on how much sun it sees, humidity, temperature, etc. DON'T PANIC!!! Be patient and don't mess with it!
10. Stand back & admire your handywork. Be careful to not twist your spine as you pat yourself on the back!
