Over the years, one of the small drawers of the Secretary Desk had gotten a corner damaged. Repairing it with carpentry would have been a pain, but a furniture restorer gave us the tip that if we were going to paint the piece (not stain) we could use Bondo to make a new corner. I also used it to repair a crack in another drawer front.
Bondo is a body filler used in the car industry. When it’s two components are mixed, a chemical reaction is produced and it will generate some slight heat. At this point it can be molded like putty. You can find it at auto supply shops and now at Lowes in the paint area.
When using Bondo:
1.) The work area should be clean, devoid of dirt and polishes.
2.) Lightly sand where you want it to attach. It needs an area to grip and if the surface is smooth it will have problems.
3.) Work in a very well ventilated area and use latex gloves. This stuff can be toxic.
4.) Once dry and hard, it can be sanded and painted, but not stained.
5.) Use where small imperfections or defects need to be corrected. It is very liquid.
There are also other repair products out there and if you have a moulded piece to repair check out this post.
