Fibreglassing a car,to do or not to do

[Donovan D]

Is it adviseable to fibreglass a car?
As I was messing about on my bus today a guy stopped and came to have a look, its a friend of a friend.
We talked about a few rust issues I have and he said he will give me a quote on fixing it, but not with metal with fibreglass. I'm not really keen on this idea, but what are the real pro's and cons of this?
Views and opinions please.

If the car isn't made of fibreglass to begin with, then friends do not allow friends to use fibreglass on their cars, ever

Waste of money and time as well. Ryan's 66 has half a fibreglass floor pan and its all falling out at the moment.

I will have to look at this tommorrow. Do you know a welder with some sheet metal??

I have used fibre glass for repairs with mixed results. But for major rust issues it is not advisable as the rotten parts still stay there and will just rot further. Rather cut and weld.

Hi All,
Fibreglass or not that is the question ????????????

To put it in technical terms..................... NO !!!!!!!!!
Fibreglass is not water proof as a lot of persons believe.
It is the paint over the top that makes it water proof.
This means that all that is covered will stay moist for ever and rust ,unseen, forever.
The correct way to handle rust, is determined by the level of restoration that you want to follow.
Full restoration to new, Cut and re-weld (tig or mig) new parts, rust proof, and paint.
To keep original, STOP rust with rust converter, Air seal area with paint or rubber riser, sandwich area with new steel that has been treated, one side or both depending if it is seen or not, to return area to full strength, re coat area both sides to stop air entering joint.
Patch Up Job, cover with fibreglass and sell as fast as possible.
This is only my opinion, which may not count for much..................................

Leave the rust alone, it has feelings too

Lol, splits find someone who has a mig, tig welder and knows how to weld, and have them patch it up for you.

Better for the long run.
