Could my wax be gone already?

[TOGWT]

Collinite is a hybrid wax (i.e. it contains polymers as well as wax)

Polymers need a porous surface to bond to (they do not do well if oils / water is present) they initially adhere by surface tension and then after a period in which the solvents in the carrier system vaporize (outgas) the polymers cross-link to form a covalent (molecular) bond to the surface.

The initial bonding in this case was to NXT, once its (very) short durability is gone the Collinite bond is lost (a chain is only as strong as its weakest link)You might want to use a polymer with better durability than NXT as your 'base'

Ensure that the surface of the vehicle can be left undisturbed and free from rain and water (condensation, dew, etc) until the polymer has cross-linked (usually 1 - 24 hours) or the surface protection may be compromised
