for sanding: Putty: initial sanding P 180,
final sanding P 320. Surfacer: dry P 400,
wet P 800. |
|
Follow specifications in
the Technical Data Sheet on drying the surfacer. |

When the middle coat has
dried through, finely sand and polish the

For deeper
score marks, sand and apply another coat of
middle coat. |
