HOW TO APPLY GRIP:

Step 1:
The basic tools for applying GRIP to racing tyres include a scraper   - a household decorating type will do fine - a pair of latex gloves , a paint brush and an open container in which to pour GRIP
Basic Tools Needed
 
Step 2:
It is important to clean up the tyre surface with the scraper to remove any built-up rubber.  This will allow GRIP to penetrate more evenly throughout the tyre surface and also helps to prepare the tyre for the next race.

Pour some GRIP into the container and then brush on to the tyre's tread surface  - there is no benefit in applying it to the sidewall.  The first coat will probably take 20-30 minutes to absorb, depending on room temperature.  Further coats of GRIP can then be applied as desired, leaving similar absorption time after each coat.  Four or five additional coats will give a significant increase in adhesion (durometer reading about 10-15 points lower).

Step 3:
The tyres must now be left to cure. This will take several days.  It is a slow but necessary process to ensure the tyres are softened adequately and that GRIP has penetrated down through the tyre.  Because it is non-evaporative, GRIP will keep on penetrating and tyres will stay softened for weeks

REMEMBER:
After the tyres have been used, the softness can be maintained by again scraping off built-up rubber and repeating the softening process.  Once more, allow several days for adequate penetration.
