New or refurbished alloy rims may have coatings and lacquers applied to the alloy surface. Also when the rim paint is being dried, waxes can come to the surface creating a low surface energy (non-stick) and not allowing the adhesive weight to properly bond to the rim.
New or refurbished alloy rims may have coatings and lacquers applied to the alloy surface. Also when the rim paint is being dried, waxes can come to the surface creating a low surface energy (non-stick) and not allowing the adhesive weight to properly bond to the rim. For this reason it is essential to clean the rims where the weight is to be applied to ensure that there are no traces of chemicals on the surface (eg wax or silicon).
Failure to clean the rim can lead to adhesive weights falling off within days of fitment, causing balancing failure.
