  • Need some encouragement...

    So I want to start fiberglassing my trunk, and I wont lie, I'm terrified! I've read two really good tutorials:

    http://www.gadrivers.net/~dwicker/fiberglass.html
    http://www.the12volt.com/installbay/...TID~74519~PN~1

    The first one is EXACTLY what I want to do. The second is just a general fiberglassing tutorial, but it covers the topic of attaching to MDF with fleece.

    So far, I have:

    - the subs (2x 12" kicker cvr aluminized)
    - fiberglass mat (7x package of 8 sq.ft.)
    - resin and hardener (2L of resin, plus the hardener that comes with it)
    - blue tape
    - gloves
    - dremel attachments to cut
    - speaker terminals and 12-gauge wire

    and I need:

    - money
    - wood dowel
    - MDF speaker rings
    - courage
    - friends to stop working so often

    Does anyone have any suggestions to help me out? I don't want to waste hundreds of dollars of materials because I mess up something so simple.

    Hi Colin,

    Sometimes with tasks which feel so daunting you just have to try doing someting on a smaller scale first to both get the skills honed and convince yourself that a larger more complicated task will only take longer.

    The time to do a task is proportional to its size and complexity. Don't expect it to be a quick exercise, especially your first.

      IMHO, give it a go. What is the worst thing that can happen? If you make a mistake, just try again. As Kev said, try something small first to get your confidence up.

      As long as you add enough hardner so the resin sets, you will be ok. Check the mixing requirements and try to get it close.

        go for it!

        go for a long estimate of time, I mean long. That way you won't get discouraged after working 2 weekends on this

        If you have the money, the time ... What do you have to loose?

          Do you have AIM?

          If you do, IM me @ exus28

          I would be glad to help, I rather have a convo then just typing broad statements.

            Thanks for the words of encouragement guys! One of my fears is that I actually don't have the money if I mess this up! But I appreciate everyone saying go for it! My buddy (no experience) is going to come down on Tuesday and try to help me out. We'll probably end up printing out instructions and tutorials and doing it VERY slowly.

              i think you can add aim users and vice versa, and i'd recommend talking to nexson after seeing his works.

                That first site says to use spam on the blue tape... please don't do that.

                The12volt is a great source of info.

                The steps:

                1 - Tape everything off with the blue tape (cause it has low stick),

                2 - then use aluminum foil tape on top of that. The aluminum foil tape sticks like duct tape, that's why you have use the blue tape first. The foil is a barrier that will disallow the resin to seep through the tape and ruin the surface below.

                3 - use turtle wax on the foil as a release

                When mixing resin, use a scale. Most important thing is the catalyst. You'd rather use too much than too little. If you don't put enough it will never cure and you will be left with a sticky mess that always smells like resin. If you put too much it will def. harden but maybe too fast... you can always slow down the curing process and extend your work time by dumping some MEK or acetone into the mix.

                Also, do small sections. You don't want to mix a ton of resin get a tiny section done, and be left with with a gallon of harden resin that you can't use.

                  Okay, I've seen people using aluminum foil on top and taping that in place. I think that's a smarter idea anyway. Can I put the pam on that instead? I don't have turtle wax lying around so I feel like pam will work. On the foil though. Got it.

                    I have had no problem using pam on top of tape. When you use foil, you lose the shape a bit and it is hard to work with because it is not stuck to your surface like the tape is.

                    When using Pam, some of the tape stuck to the mold, which really isn't a big deal. Now that I am more experienced, I learned you can just use MOLD release. Put on about 3-5 layers, while wiping off each layer before you apply enough one.

                      You don't just put loose foil on the tape, you use foil tape which will keep the shape perfectly just like the blue tape. Or for large areas you can use sheets of aluminum foil (from the super market), spray some spray adhesive on the dull side let it tack then put that on top of the blue tape.

                      Again its not loose (either al. tape or adhered al. foil sheets).

                        Oh, I've only ever seen aluminum sheets taped to the form. I don't have aluminum tape, and I don't wanna waste money on it since that stuff is EXPENSIVE. I'm driving down to the states right now actually, maybe I'll stop in a hardware store and buy a few things!

                          Here's what I did today. I bought that wood like I said I would. I want to use the spare pieces as the "dowels" since I have it on hand already. My buddy is going to cut these out for me soon, and if he doesn't then I'm going to the old high school shop to get my favourite shop teacher to cut them up for me.

                            Yeah, don't do that. That's where you'd loose the shape like Nexson said.

                            It is expensive but the easiest setup. If the cost is out of the equation, use the alum. foil from the market and get some spray adhesive (3m stuff is great). All together it shouldn't be any more then $10 and should cover a ton of area.

                              I called my old high school. The shop teacher loves me (me and one friend went overboard for every project, we were the only ones allowed to use his table saw) and told me to come in during his 2nd period class tomorrow at 11 AM to cut out my subwoofer rings. So, I'll do that.

                              I bought materials today (mixing cups, free stir sticks, spray glue, aluminum foil, tape, wood glue, etc) so that we can start fiberglassing tomorrow at around 2:00 PM. I'm having some friends over for a few drinks and to help me out. I'll try to snap pictures to see how you guys helped out

                              Im excited now!! Still worried.
