If you have big holes, cracks, or broken edges to
repair, bondo works the best. There is no
shrinkage or cracking when it dries.
A quick note here. Use only when you are painting
your project. Pretty blue or pink bondo obviously does
not look good with lovely stained wood.
Bondo is a two part process.
There is the stuff in the can and a hardner in a tube.
When the two are mixed a different colour is created.
You must not forget to add the hardner.
I have been busy and not paying attention and
have bondoed everything and forgot the hardner.
You then have to go back and dig and scrape out
all your work. Aaah!
Follow the directions on how much hardner to add.
Wear a mask and use in a well
ventilated area.
Mix the two ingredients together well.
You have to work quickly as the more hardner you
add the faster it dries. When it starts to go from a spreadable
paste to a gritty mixture time has pretty well run out.
I leave a bit of a raised area of bondo where the hole is.
Other than this, I try and scrape all the excess off.
After the bondo has dried, which is usually under 10 minutes,
sand off with 150 or 180 grit.
