    More Layers After Drying

    The place im working in my El Camino is very cramped and i dont want to spend a lot of time cramped up. Can i lay down like two layers of glass and let it dry then pop out the mold and apply more? Also can metal mesh i.e. window screens work to strenghten enclosures with the combo of glass? Thanks a lot!!

    Re: More Layers After Drying

    Thats exactly the same thought that passed through my head. But would it be okay to glass like 2 layers down, pop the base mold, then glass more on that?

    should be fine as long as the ejected mold is not thin.

    You can glass 4 or 5 layers at a time. Use big sheets of the mat

    my initial thought is that it won't add to the strenght as it won't soak up the resin and the resin by itself would crack..... does that make sense?

    Re: More Layers After Drying

    I do not believe that the mesh will make it any more stronger than an extra 2 layers of heavier matting will. Its going to cause more problems later, just use more matte. Also, the rule of thumb on releasing your molds is at least 3 layers. If its too thin, then when applying the rest of the layers on top, the reaction of the resin and the catalyst (mekp) is exothermic, thus releasing heat. If the mold is too thin and gets too warm, it can actually warp and not fit back the way it was when. Which kinda defeats the main purpose of fglass in the first place ( to be able to accurately use odd, curved shapes for a custom fit). Are you doing kickpanels or what? Why not remove the seat for more working room? 3 or 4 layers of glass should only take about 4 hours or so to complete. You can begin laying another layer as soon as the resin is dry and non-tacky to the touch. And as someone already mentioned, you can do 2 layers of matting at a time. So in escence, by doing 3 repeated layers, you are actually laying down 6 layers of matting, so you should be fine with that mold.

    You should be able to glass layers right onto the mold now, and window screen wont work.
