This is mainly for when there is inclement weather and your buggy is at risk of turning into a rusty ornament. A light coating of GT85 on the metal parts and bearings should help to mitigate against this issue.
Between Heats and Finals, we have an air compressor available for use to blow off the worst of the AstroTurf fluff from your buggy. You can then use a rag to wipe off any remaining residue.
