Most auto parts stores sell the fiberglass cloth in large sheets.

Check out West Marine or other boating store.

Home Depot or Lowes

I've been trying to find the stuff I need to do this but I have been having a little trouble. Where can I find the sheets and resin at a decent price. I checked at Wally World because I had seen it there before but all I found were kits for small repairs. Can I get the stuff from like Autozone or something?

That's correct....leave the foam.

ah good idea

[Black_peter]

IMHO:
Shape the part you want out of foam.

Make a plater mold out of the foam part.

Sand the plaster smooth
You can use a thin mix of plaster and
"paint" a coating to fill holes and such.

rub vasiline into the plaster and glass away!

[LS6TT]

ok so foam, then clay over that
(then remove foam? or leave foam for stability just make sure none is exposed?)

then spray pam on the clay?

or just lay the glass sheet on it, resin etc ( know the basics of glassing, just never done molds, only done consoles and speakerboxes)

[BucKatana]

Hard foam is porous and as a result the resin will seep into every little nook and cranny. Removing the finished product will be impossible.
Once the foam is shapped you will have to spread a harder compond over it. You can use plaster,clay,bondo etc.

Sand to the desired shape, sand some more......then a little more until baby ass smooth. Then prime,paint and clear.


The idea is to have the finished surface of the mold as smooth and perfect as possible. The closer the mold's finish is to a glass like surface the easier the fiberglass will lift off once dry.


fire away if you have anymore questions.

Buc this is aimed at you given you seeem to know the most in this thread

if im making a mold using say hard foam ive shapped.

do i spray Pam on the foam then lay the glass cloth?

[BucKatana]

Ah...plaster.
Yep...I've used that aswell. Much easier than clay or Bondo!

I like your baking soda trick.... I have to test that out on my newest project. heeheeheeee..

Good advice Buc...
I found some good "how tos:"
One was from Hod Rod magazine..
The other was from a guy who makes
Gundam costumes..

Damned If I can remember the links.. (

Couple of more suggestions:
I had no problem with the "female" mold..
Worked reallt well for me.
Mixing baking soda with the resin give a
surface that sands really well.
If you make a mold out of plaster use
Vasiline to keep the resin from sticking.

Plaster is good for a mold as you can sand it smooth and add a "coat" of plaster to erase mistakes.

Fiberglass is a wonderfull medium to work with. It will take the shape of almost any mold.
It is however very messy and sticky.

The most important things to keep in mind are.

Preperation is the key. Have everything ready and on hand before you mix the resin. You have a very short work time once the hardener is mixed with the resin.


If using a mold to lay the glass .....use a male or positive mold. It's much easier to lay over something as compared to laying "in".
Also...the finished surface will be smoother.
Having said that.....the surface that the glass is to be layed over needs to be perfect. Any imperfections will show up and result in more finishing work.

Use a mold release to make removal of the dryed glass easier (possible at that ).
Spray on Pam cooking oil works really well.

Lay one or two sheets of glass and let dry. Remove from mold once completely dry. The product will have enough flexabilility to allow for easy removal. If you apply the total amount of sheets all at once it is harder to get off the mold.
Then place over mold again and apply the remaining sheets of glass and resin.

There are different thickness of glass sheets and carbon fiber sheets. The 1st few sheets should be of a thinner gauge if the mold is highly detailed.

Hope this helps some.

I made canoe, it lasted for a year or so. Lets see some picts?

The only fiberglass work I've done is repairing the nose of my surfboard. 3 times.
Hey, good luck with the project and keep us informed on how it goes.
