| Rising Putty,,,, Need advice |

O gotta find the site tonight, (It may be Muhati's site) but someone has a tutorial about a similar substance to bondo but it is much thinner and can be used on surface problems. It is still an epoxy type mix but thin like thick syrup. apparently you can get near razor thin and then the sanding is really a breeze. (II personally have not tried the stuff but am very interested). I have used and like a metal putty knife as well. I will add that to the WIKI. |

Metal is not smart. If you let the bondo adhere to the metal, it will be stuck on there permanently. The advantage the plastic one has is that you can leave a bit of bondo accumulated on the edge and you can peel it off with no residue. Also, a useful thing to have is a cheese grater. You can add more than enough bondo, without being smooth with it to whatever you are patching, and about 5 minutes after curing you can cheese grate the excess until you are somewhat smooth. After it dries, then you can sand and you should not have much excess bondo to start sanding with. i'll take a pic of one when I get home. |

For the most part my old putty seems to be okay.. However "the most part" is not good enough for me! There are a few parts that had still risen even today. It's been almost 3 weeks now... I don't want to spend forever trying to dig these out... I have to admit to something I tried awile back...Some I redid and mixed the putty with tightbound wood glue. :-[ I thought it might help. Anyway their in good! What if I just sanded it enough to make a slight divot in the putty and then a thin layer of Bondo??? Any thoughts? |

With the metal putty knife I was able to wipe off most of the Bondo before it dries and still sand or chip away anything left over. The plastic putty knife ended up getting damaged when I tried to remove the Bondo later, and then left big grooves the next time I went to apply Bondo. Thanks for the explanation about the cheese grater, I was wondering why people were suggesting that. Marlboroman13, sorry I've never tried it, so I'm not sure what would happen. You're probably better off starting over with Bondo and saving some time in the long run. |

I got bondo stuck to my putty knife, but sanded it off with my electric sander in about 10 seconds. |
