Hey guys, I read in an old thread here that you can use blue painters tape to cover the styrofoam when you are glassing . It has been recommended to me to use aluminum foil but i having a hard time getting the foil to lay flat and preserve the lines of my seat. Is it reall ok to just use blue painters tape and no foil? thanks
 
Nevermind. I just wraped it in tape and cling film. Ill put some turtle wax on it before i glass it.
 
I tried the foil too, didnt work cause it kept wrinkling. Wasnt worried bout the wrinkles showing in the glass, but was more worried it would get stuck IN the glass. Painters tape and turtle wax worked fantasticly.
 
Haha yeah i wnt with tape and wrap. I think Im gonna either try turtle wax or tri-flow on it to keep it from sticking. Ill post some pic up later tonight. It's not gonna be the best looking seat but I think it'll work for what I have in mind.
 
i have glassed quite a bit and all i have ever used is 3 layers of blue tape....

once the glass hardens you can easily pull the layers of tape apart and no damage is dont to either surface.....
 
Something else that works quite well is packing tape. The only down side is that it can be hard to see the areas that you taped because it is so clear once it is attached. Nothing sticks to it though. No wax required.
 
based on the title of this i thought you were gonna cover your seat with either blue tape or foil and you wanted our opinions..

hahahaaha
 
Haha yeah I guess I still have to decide what I'm goin to upholster the seat with. Can anyone recommend what type of fiberglass I use?
 
I just used the stuff i found at AutoZone. Worked great. I did about four layers of matt, then one layer of woven cloth matt, then one more on top of the areas that needed strength. Thing is solid as a rock.

So, did you guys use a quart, or a gallon , or 2 gallons? how much should i buy...???:-k
 
If you are glassing over blue foam use epoxy resin. The epoxy will not eat the foam. Poly resin will dissolve the foam.

It's also incredibly stronger. Just ask anyone who has made a small wooden boat, canoe, or kayak. I heard that some people use spray Pam as a release agent. Anyone?
 
As O C and Pauly mention, if you glass directly over the foam using the epoxy resin you will end up with a really strong form. The only downside is cost as epxoy resin can be 2 to 3 times more expensive than standard f/g resin.

I've built a few seats with this method and it works well. I also think it is easier & quicker than taping over the form or "skinning' it in preparation for the cloth and glass.

Just some more options for you.

so then, how much do you use on an average seat pan? a quart?
how many layers of cloth, on average?
 
A pint will do for your job. You will want a few layers of cloth. Once you think you have what you want the foam can be dissolved out leaving just the glass part. Then if it is not stiff enough you can add more material

Another option is to trim out most of the foam and leave a thin layer and apply a ply of glass to the inside and you will have a sandwich construction.
 
so 3 layers or 4?

mat or that woven cloth?

does it matter?

Your choice on fabric, I just work with cloth. There are so many variations in the fabrics that will vary there formability and strength characteristics one can not just say 3 or 4. Each part and each layup have there our caricature.

The more curves the stronger the part and thinner it can be. Flat areas should be thicker.
I have made tail sections with one ply of 8 OZ cloth that were fine, but a bit fragile. There was no taillight hanging off it though.
