Is this best applied by hand or pc ?
Will it leave a white residue behind or stain trim ?
I currently have 2 coats of 976 on all winter and its held up fantastic but I'm sure it's starting to diminish as it's been through many washes , but still beads and shines very nice.. Just feel the need to spruce it up since it is nice outside . I have not tried the 845 to any extent yet so advice is appreciated .
