55 chevy pickup cracked body filler

[wilberweb]

Hi, guys thanks for the post.
I have started to remove all the filler and start over. I was thinking I should but wasn't entirely sure, but my gut told me I should take it all off. what I did find is that I used glazing compound to level out the low spots then filler over the glazing compound, and I think that's why it started to crack. I noticed that the glazing compound didn't set up, and was still soft. So apparently you cant put filler over glazing compound.
So luckily I caught it in time before I went further. I think if I would have left it I would have major problems when the paint went on.

Thanks for all the advice.
I can always turn to this forum for some great advice.

You may never stop the problem. Those roofs flex way too much. Even heat/cold cycles will flex them enough to crack many fillers. You may have better luck with "kitty hair" or the likes, but if your roof is in bad shape I would suggest getting a new skin. If you need proof, just push your finger down near the middle of the roof and you'll see just how easily they flex. Just sayin'.
