New Hampshire International Speedway has applied high-traction sealer to parts of the Loudon, New Hampshire track’s road course to eliminate slick spots under rainy conditions. The track will also apply the sealer to the entire NASCAR oval in May, prior to the arrival of the AMA National scheduled for June 15-17. The goal, according to NHIS Safety Director Jerry Wood, is to “not have any slick pavement in the wet or dry.”
