Questions about bondo...

Alright, my dad told me that bondo won't stick to plastic (he's had a lot of experience from using it on cars), and that it won't work for using it on a plastic case. However, the results of frankencases that some people have made here beg to differ, and I have some questions about the stuff...

1. What kind of bondo should I use? I know that there are different kinds, and some probably stick to plastic better then others.

2. How should I apply it, and how much should I use?

3. Anything else I should know?

From experience, I can tell you it sticks to plexiglass/styrene/acrylic well, having used it on them. No problems there.

Also, most console/portable factory-made cases are made out of ABS, the source material for most frankenmods, and it adheres to that very well, as you've seen.

And a large number of car bodies are made of ABS as well, and of course, bondo is made for cars!

As for the kind of bondo, I use just standard, run-of-the-mill bondo from my hardware store. Although many say that spot putty works better, seeing as it dries faster (so I've heard) and can be used for large areas as well as tiny cracks. People say marine putty is also good for contained areas and small crevaces/cracks, but many have also said it's far too runny for portable use and dries very slowly.

To apply bondo, use either a wooden spatula or a putty knife. The latter would be better, because it is specifically for bondo applications and such, but a spatula will get the job done. And for how much? It differs from project to project, but it's fairly easy to eyeball once you have the mixture right in front of you. And even if you add too much, you can just scrape it off when it's wet and then sand it!

Good luck, man!

The bondo I use is Duraglas fiberglass reenforced waterproof body filler the hardener has instructions on how much of it to use and such, at wall mart and places they only have the Bondo brand and they sell alongside it these nifty little plastic paddles that are actually designed for use spreading bondo, pretty much any kind of body filler will work but you must rember that you will be sanding it and to get a good smotth finish put on slightly more than you need then sand down to the level you want and get some Bondo spot putty to cause there will almost definatly end up being some air bubbles in it that will have to be filled remember that spot putty shrinks so it may take more than one application to get it smooth
(you can trust me, I grew up in a body shop)

show him dkaps work

the bondo meant for cars that comes in a big can sucks for portables compared to the 2 step bondo method

first use marine putty (its pretty strong and holds nicely)
then use spot putty (its really smooth and fills in very nicely)

the bondo you buy at wall mart is the same stuff that comes in the big cans for cars just in a smaller package.

*whisper*I pioneered this method by accident, and it turns out it owns!

Also, this is random, but use superglue over epoxy anyday. It's a stronger bond, easier to work with, and when combined with the marine putty, its just utterly perfect.
