easy mac greasy, wear your protective gloves is my advice, tacky, dries overnight, follow the direction if you want too it might allow you to install your filter in less drying time.

spray filter cleaner works GREAT! as well does the spray oil this can will last thru many filters.

Very tacky, Blue in color so you can see the coverage on the air filter.
