How To Apply 3M Finish Glaze – Collision Repair Training

This video demonstrates how to apply the new 3M and how to sand the glaze. Once sanded and featheredged, you’re ready to mask and prime with epoxy primer.

HOW TO APPLY TRADITIONAL FINISH GLAZE

In this video a BCC student demonstrates how to use traditional glaze.

Benefits Of Using Finish Glaze

• Can be applied over sanded body filler, sanded primer, or sanded paint.  I would recommend to sand with a no finer grit than 180 to assure proper adhesion.  Glaze will not stick to non-sanded substrates.
• Spreads smooth and sands easy.
• Can be applied over small dings and dents without removing factory e-coat corrosion coatings.
• Minimal Shrinkage

Disadvantages Of Using Finish Glaze

• Costs more than body filler.
• Can not be applied as thick as body filler.

STEP BY STEP PROCEDURE

The body filler has been block sanded and finished in 80 grit sandpaper.  Now you are ready to feather edge and apply glaze.

1. Feather the paint edges around the repair area with 220 grit sandpaper on a DA.  Sand each layer of coating to expose at least 1/4″ of each coating.
2. Blow repair area with compressed area to remove all dust.
3. Apply (either type 3M or traditional) glaze from paint edge to paint edge.  (slightly overlap onto the sanded painted surface.)
4. Allow to fully dry and block sand with 80 grit sandpaper. (just knock the highs down…do not sand on the painted surface to eliminate 80 grit scratches on paint surface.)
5. Apply guide coat to help identify highs and lows.
6. Block sand glaze and finish shaping with 150 grit sandpaper.

That is it!  Now you’re ready for primer and paint.  We’ll hit that in another lesson!
