I am in the process of redoing my headliner. It started sagging about 3 months ago and i just cut it out and left the board in. My girlfriends coming down next week and I wanted a better look so im fixing it. I noticed some weak stress points with all the fabric off. I grabbed a product called "bondo-hair" ( I kid you not). I have never worked with fiberglass, so this was a first. It was like pudding with fiberglass strands in it. It adhered well to the headlinerboard. I hope I have not ruined the board? It feels much stronger now. I will be recovering tomorrow with Mom's help shes redone enough chairs she should know what shes doing. I am simply wondering if the fiberglass stuff was ok to put on it?

ps- it was the guy at advanced autoparts suggestion

LOL

I dont see it hurting anything, you should be fine

bondo hair is that kinda like kitty hair?

its a fiberglass stuff with little fibres in it. i have read about it sounds like a good way to fix that. let us know how it holds up. and how the board likes it if it adhered or not.

i dont think you should have a problem with it at all as long as it is still smooth on the side that the fabric is going on ....
post some pics when you get it done so we know what is good or what is not ...

Well finally got everything finished. For a first time job everyone thinks it looks great. The ONLY fault is that on the inside corners you can see the back of the board. None of us knew how to cover that. But the main thing is that you can now look up to see nice clean gray material and not ugly residual foam backing from the material. As for the "bondo-hair" it worked just fine. I messed up a little on the last application because i put too much hardener in the mix. It adheres fine and stiffened the board up nicely. From what Ive been looking at I guess i turned out fine becuase none of my clips broke in the front I will try to get some pictures from my friend. I have no camera

yeah post some pics soon id like to see.....it sounds like it turned out just fine

be carefull with that stuff, Applying a second batch (ie every time you mix a bunch with hardener, you have a batch) before the previos batch has cured creates a fire hazard.

The outer layers trap the gasses that form during curing beneath them, stopping the curing process.

if the fiberglass ever cracks and that layer is exposed to the air, it will begin curing again. When fiberglass resin cures it lets off heat, when that heat is burried under a bunch of layers of fiberglass, it is well insulated (can't escape) and can build up enough to start the fiberglass on fire.

A corvette owner in windsor glassed a few parts of his old corvette. three years later, the repair area cought fire in his driveway.

I had a hard time believing that corvette story happened, but the physics of the situation iare quite possible.

now that sounds like something for ripleys believe it or not...lol...that would suck if it happened i havent heard of anything like that before ...but anythings possible i guess

Should've done it right the first time if you don't want Ripley at your house.
