Official Bondo Thread

also, you can mix bondo with resin and hardener to make a milky sauce to put insid eof vacuformed shells to produce a copy, like *soemone did with a kroenen vacuformed mask from hellboy

Bondo smells! I opened my can yesterday and was not prepared and was breathing normally...took in a nice full breath of Bondo fumes and had to close the can immediately since I was so ill from the smell.

If I use 200 grit sandpaper on my helmet dent (I do not have 80 grit), will the bondo stick? Same for Sintra, Do you have to grind stuff up for this bondo to stick?

200 grit? Oh ya, make sure you layer it. In that i mean instead of trying to fill the hole at once, apply several coates and build it up, let it dry between coats, think bondo likes to crack open and if its to thick it will never harden.

So I just bought some Bondo to play around with and get used to before my 95DP comes in. I noticed today mine was red whereas most of the props-in-progress I've seen online has has more of an off-white color. Did I get the wrong one?

All the bondo I've ever worked with was grey, the hardener is a dark red and when you mix the two together it turns a pinkish color.

You probably bought this;

That's what I used on my fett bucket. No mess no fuss.
really cuts down on air bubles & dries really fast.

The bondo spot putty is not suitable for large, thick areas like the dent. It's designed for things like pits and scratches, sorta like spackle is used in drywalling.

how long does Bondo last?

Before I bought a new can of Bondo the old Bondo was looking bad. I had the old can for over a year.

Thanks. ;)

hhmmmm..Do you mean shelf life? Well if you opened it a year ago well its not good to keep it that long without use. Another issue could be if the Bondo was placed at room temperature all this time or not.Temperauture is very important.

The kind of bondo you want to get comes in a 2 part mixture.
Usually in a quart-sized can with a small tube attached.
The can is the main part of the bondo and the tube is the hardener. You MUST mix the two together. Too little hardener it'll take forever OR it'll never dry, too much hardener and it'll dry before it's mixed.

I usually use about a golf ball size amount of the main bondo (the grey stuff) and mix it with about a one inch (25.4mm) line of hardener. Mix the two thoughly so there are no swirls and it is one soid color overall.

Hope that helps. PM me if you have any more questions.

Usually I have seen a can of the actual bondo lasting two years tops. This is at a constant temperature around 50-90F.

What I have seen happen alot is the hardener or catalist hardening or seperating. But you can buy new tubes...hoever think about this. IF you are workin on a $150 bucket would you want to chance putting bondo that won't cure on it? OR spend the extra $10-$15 to get a new can?

I've had cans lying around, and I try to use it after a year and most of the time the part in the can has seperated and has become clumpy. Even trying to mix it doesn't help, like Prymer13 said, you might as well as just buy a new can :D

You would be crazy to use the old stuff..Spend the money and buy new stuff. Take it from me I just did my rifle with some bondo that was pushing the age in a can. It took well but I wont take that chance again.

Though I agree with fettcicle the bondo in the old can was becoming clumpy so I bought a new one. ;)
