  • Fiberglass....after bottom layers put on

    Hey everyone, ok i made my fiberglass box not long ago and was wondering what i should do with this situation. Ok i read before that if you have air bubbles then that can make your box weaker or something like that, and when i made my bottom layer for my car i didnt have a roller or anything to get the bubbles out, i tried my hardest to keep them low when i was glassing until the last 2 layers when i got lazy. Well anyways now i have the bottom of the box ready for the next step with 11 layers(yes 11) and was wondering if its not strong enough because of the air bubbles...or will it sound crappy cuz of the air bubbles? Well i would think 11 layers would be just fine and dandy Well please tell me what you think i should do. Here are some pics of the bottom layer of the box....i showed close ups so you can see the air bubbles..

      it's probably ok as long as the air bubbles are near the outside layer, not in the middle, and not on the inside. If they're on the inside, just crush them and sand them down and fill with bondo (or don't fill them)...

        bubbles in fiberglas...

        11 layer will be just fine... if u mean a sub box i use to put sand on a couple of layers in the middle. the u will have a little heavyer box, with a lower res. freq.
        even if u have bubble in the middle 11 layers will be enough... 11layer is over 1cm thick....

          yeh its a lot more then 1cm....i used a lot of resin(been doing the bottom layer for 2 weeks....i put a lolt of resin in between so it took 1 day for every layer...sometimes even a little more ) I'm thinking ill sand it down, then add body filler in the gaps, or even give the whole thing a skinny layer of body killer... or maybe sand it and then spray rubberized undercoat to makew sure everything is sealed..(or dynashield...but thats more expensive)

            11 layers is a bit much. i used 3 for my subs and have about 3/8" to 1/2". from what i have read in another car forum you need to still use some kind of mat-thats where you get your strenght. check this out under forums and then fabrication:
