Phil the gell coat is your color coat it is sprayed in the mold first. then cured then the chopped fiberglass is sprayed in then rolled by hand, and then layer by layer.

The point is the spraying of the epoxy by itself is not very strong. Its the fiber glass that gives it strength. Epoxy is just a fancy glue, that burns like hell and very toxic and gives off vapors unless sealed by a paint.

Aye, that's the point. It's quite flexible. It just forms a layer ontop the metal. That's what a layer of waxoyl does. But waxoyl is washed away after a year or two. And if a crack forms in the epoxy, left and right of the crack the epoxy still adheres to the metal, making it a "controlled" oxidising area.

I dont want it strong. I want it to protect the metal.


In case of the footwell I used a glass fibre mat, and thats plenty strong for that hole as I dont go tango on that spot. I wouldnt use it for the floor, surely.
 
no it wont it will end uplike powder coating ,waxoyl is something put on to protect ,shed water etc its not paint different jobs ,your patch will fall out cant believe you did that ,why not weld patch on ,epoxy is no good on old landy

no, it wont. You will have a hard time UNsticking it if you will ever need it.


erm, steel flexes min 10 times less before breaking stress compared to epoxy. And epoxy is not a sheet. For boats: You put the glass fibre mats in a form, and pour epoxy glue on it. The mats absorb the glue, and out comes the form you need. In our case, the form is the chassis, and we dont have mats, but that's no problem (experience)
I'll have to remember making some piccies tomorrow. I mended this hole with a glass mat and epoxy:

No, they wouldnt. You dont want your cars last THAT long, it's quite heavy and more cost than you need. And they do use other things on the metal form the inside, so in some way they do...

And for those who ask why: Cant weld if there's no power outlet where you want it fixed.

And I didnt have a welder back then.
 
You could have stuffed it with newspaper a skim of polfilla and pop riveted a baked bean tin over the top to take a magnet, still dont make it right.
 
Maybe doesnt make it right, but keeps the flung up stones from the tyre from hitting my right foot at 40mph down a ****ing gravel road. And right foot doesnt get wet on the autobahn when it rains.
