For best results, tyre lettering needs to be installed in the upright position. Do not try to work upside down. Do the top section, on all four tyres and roll the car. It is much easier when the letters are not upside down.
1.All kit materials and tyres must be dry and kept in a climate no colder than 18 Degrees for a minimum of one hour before installation.
2.A light sanding of the sidewall is needed to knock the edges off any textures on the tyre surface and add more surface area for the adhesive to create a superior bond. It is not necessary to sand the sidewall smooth but if you have an electric palm sander, it is very easy to sand a tyre sidewall completely smooth for that authentic racing look.
3. Clean the tyre sidewall with rubber cleaner or a strong degreaser thoroughly and let dry. Repeat this step (sometimes up to 5 times depending upon the residue buildup or if tyre shine has ever been used) until the rag comes away clean with no new residue. You also know you are done when the rag does not want to move in a scrubbing motion any longer due to excess friction from the clean rubber. If your tyre is not sufficiently clean, the letters will not be permanent! Next, use 150 grit sandpaper provided with your kit and buff over the area where the letters will be applied. A final wipedown of the sidewall and letters with high percentage Isopropyl alcohol is the final cleaning step.
**DO NOT TAKE THIS STEP LIGHTLY! YOUR KITS WILL NOT BE PERMANENT IF YOU SKIP ANY STEPS. DO NOT USE CITRUS BASED CLEANERS OR OTHERS THAT LEAVE BEHIND AN OILY RESIDUE**
4.Apply glue to the outline of the rubber letter, then fill in letter thinly and evenly distributing the glue. Do not use so much that it squeezes out and runs. Best results require a thin, even coat.
5. Apply light pressure to letter, letting glue set for 15-30 seconds while rubbing from centre to outside of decal to remove air bubbles.
6. Let set for one hour for proper adhesion.
7. Remember, If you need to letter the bottom of the tyre, wait for the top to cure and then rotate the bottom into the top position. It is not necessary to remove the wheel but in some applications it makes installation easier.
8. Simply clean your letters or permanent walls with Jif house hold cleaner and a nylon scrubbing brush.
