I'm having trouble with Bondo. After replacing rusted out metal in my 64 F100, the bondo I'm using to smooth it out, dries after a couple minutes. So dry that it won't spread. Do they make any slow drying hardener?
Experiment a little on something that doesn't matter. ...you also don't have to use the whole tube of hardener all at once.
There's a happy medium if you put to little in it it won't harden correctly and you'll have to do it again.. when its hot you just have to be very quick!!
I had a similar issue with fibreglass resin. I dumped a whole tube of hardener into it. I thought I had a plastic container full of thermite! And, yes, I was drunk.
Had an old body shop guy tell me to add a couple drops of fiberglass hardener to the Bondo mix . He said it will keep it open a bit longer & give a little more work time ?
Adding the hardener makes a chemical reaction that happens faster as the temperature goes up. Try less hardener in high temps but make sure it is completely blended or it will not set up.
It's hotter out, so the inital hardening is going to kick in faster. As was mentioned above, the bondo gets hot anyway, but you're starting out at a hotter temp to begin with during the summer, so the hardening kicks in quicker. Figure every 20 degrees over 70 F is going to make the bondo cure twice as fast as what is listed on the can.
Uhhhh, in moderate weather, bondo is supposed kick off in a couple of minutes. If you're having problems getting it smooth enough, before it gets too stiff, you need to work on your technique. Spread it as smooth as you can, wait for it to get hard enough to cheese grate, shape it with the grater, allow it to fully harden and hit it with your longboard
As already stated in different words.....Two things determine the set up time with bondo, amount of hardner and ambient temperature. Adjust one or the other and it will work correctly.
It's actually too hot to use bondo right now. Use a fan and stay in the shade, as you say, inside. Try mixing smaller batches using only a spot of hardener then work up to maybe golfball sized gobs of Bondo and a 1/2" ribbon of hardener. Do it early morning or later in the evening till the weather cools down.
It's too damned hot to mow the yard. I'm sure not about to use Bondo here in Floriduuuh. You can tell by most of our answers we've used way too much bondo and other fume producing things.
I keep my bondo and hardener in the house where the ac is on until I need to use it. Helps a bit. Dennis D
Sneek in the kitchen while your wife ain't lookin and put that gallon of mud in the refer ,not the freezer ! With lid on of course, when you wake up ,itt'l work slow as winter, cause, well, it thinks it is winter ?
