How to Use Glazing Putty

There is no use in having a beautiful, modern automobile if a previous run-in with a parking lot wall has left it with a nasty scratch down one side; in fact, a scuff, scratch or dent can ruin the look of any metal, or similar material, surface. A quality glazing putty could prove an invaluable resource when looking to fix a scuff or any other aesthetic imperfection --- particularly on automobiles. The product is easy to use, but there are a few things to note before performing any repairs.

• 1

  Choose two-part glazing putty when you are buying your product. This is already combined with a hardener so it will not absorb any other products you are working with.

• 2

  Prepare the scratch of a damaged area by sanding it with 120-grit sandpaper and a hand sander block. Completely smooth the area before even thinking about applying the glazing putty. It is pointless to use it unless the area is smooth and faultless.

• 3

  Wipe away the paint and metal dust using a damp, clean cloth. Allow the area to dry thoroughly.

• 4

  Spray two coats of primer on the affected area. Allow the primer to dry naturally before beginning the process of applying the glazing putty.

• 5

  Squeeze a dollop, about the size of a marble, of the glazing putty onto a putty knife. Smooth the putty into the cracked or scratched area, evening the surface with the knife as you go.

• 6

  Allow the glazing putty to dry. If you are using the putty suggested in Step 1, then this should not take longer than an hour.

• 7

  Use a fine grit sandpaper, around 320-grit, and sand the area to which you have applied the putty. Keep the sandpaper level and apply a consistent amount of pressure.
