Report Abuse A wind breaker, a sweatshirt and long pants are highly recommended for August in San Francisco. Of course if you are venturing into the central valley then shorts and very light weight tops would be appreciated. It could be over 100F in the Valley and only in the 60's in San Francisco on the same day. So the advice is to pack layers.
Bondo (putty) Bondo putty is an automotive body filler and a brand name used by 3M for a line of American-made products for automotive, marine and household repairs.
Here's a technique for applying car body filler (bondo). Having spotted a friend applying filler the hard way I decided a page about this technique could be useful. The trick is to use a steel rule to apply filler. In the photo a 1m steel rule is positioned at an angle on a curved panel allowing it to bend to the shape of the panel and highlight the position of a dent. It has to be a steel rule as they bend nice and evenly.
