Hey guys,

Im sure this has been covered I did a quick search and wasnt sure. What is the best glue to use to glue the fleece to your fiberglass mold? Also what is best to glue wooden dowel rods to the fiberglass mold?
thanks, realitycheck

I used spray glue for fleece, but don't FG over it.  Someone else mentioned using silicon caulk.  Another used a rabbet joint at the edge & staples.  For the dowels, I used FG resin with thickening agent (cabosil-aerosil), basically some inert thickener.  Make it as thick as possible but still somewhat stir-able.  Worked very well.

I've only done this twice, so obviously not a pro!

I have always seen people saying that they use a glue gun for the dowels, although I would really try and cement it in with a small peice of FG after to make sure that it isn't going anywhere since the Hot glue gun doesn't create that strong of a bond!

Why can't you FG over fleece that has been Spray glued? I planned on doing it this week when sealing the fleece & resin front mold to the existing back mold....was that description good enough?

Because the resin will melt the spray glue and your fleece will come undone before it hardens. Then you get too yank it off and start all over again. That would'nt be too much fun.   

I have always read that everybody used the hot glue gun but I just wasnt sure if that was the best method. So I figured i'd ask everybody.

Awesome, yeah I used the staple gun last time on my sub-box. I had the mdf so I could just staple to the back, but this time everything is fiberglass so I cant do that. So I guess i'll have to break out the hot glue gun. I just feel like this will take a really long time to stretch the fleece and then wait for the hot glue to dry so that it wont move.

hmmm, that's weird.

I have used the spray glue and it worked for me? I even had to pull a piece of lycra off and pull it tighter because of wrinkles and then glue it again..........maybe it's because I use Lycra to stretch over the mold.

hot glue works great on the fleece.. and if ur fiberglassing everything man why don't u just staple the fleece since u will be covering it up whats a couple of staples going to hurt??? wood glue or resin works best for the dowels.. i have used hot glue before but its not as strong of a bond as u would like to have since u will be wrapping fleece around it..

Well the only thing is I just dont think that staples will go into fiberglass well. Maybe they will I just dont want it cracking cause I shot staples into it. I ended up using hot glue on the dowels it seems pretty strong, I used a ton so it should stay long enough for me to stretch it and let the resin harden. I sure hope it does anyway. Im getting ready to stretch the fleece hopefully tonight. I just have to get my leds into place and then I should be ready!

Staples don't penetrate into fiberglass at all ( unless the glass is only 1 or 2 layers thick ). Use the dowel method.
