I swear by swix F4 low flouro wipe on paste. Its perfect and fast for the NW were temps are usaully at or near freezing . It lasts a long time and will not hurt your base. Buy it in the 250ml tube and lasts year. After cleaning I hot wax using crayon method with flouro all temp and then coat this with F4 over that. Works great, give it a try if you have wetter snow.
