Hey guys have a question.... what should i use to bond MDF to my plastic door panel? i used hot glue in a few spots to hold the MDF to the panel for now, but i know that wont hold for long. Would FG give a good bond? keep in mind that i will be building a sealed enclosure for a 6w3 JL sub, a lot of vibration to the panel. I cant use super glue type cause its to thin and run thou the cracks.

use an epoxy type glue, and make sure you can clamp the pieces together so it will bond . i would use some bolts and washers as extra support.

Ok so i tried a epoxy glue, but the hold wasn't strong enough for me.
So i cut 1/8" thick x 3/4" wide aluminum strips and bent them to the angle i need. worked out better for me.

Now its time to get out the blue tape and FG!!!!!
This time i cut away most of the bottom of the door panel to get the FG box for the JL 6w3 to fit and look right.

This guy has some good technique and attention to detail. I know i watched a FG tutorial in which they used some profesionall grade epoxy called somthing 90 that I cant find anymore but I looked into it and you have to buy a $100 dual tube caulk gun to use it and the epoxy/glue is really expensive itself andd theres no good way to save the stuff once its open.  So ive been stuck figuring out ways to get around this problem. Your's seems to be the most reliable although it creates more finishing work to hide the screws.

Writing this made me think of an adhesive i used all the time when i worked at the arcade "Amazing Goop" "Plumbing formula" its in a purple tube and has caracteristics similar to hot glue but is not temprature sensitive. you may want to get some to use in addition to your brakets to prevent rattling. alone it wouldn't be strong enough but it bonds well to most plastics and ....web search later...Here is your best bet, the Automotive fomula "Fix cracks in dashboards and paneling"

Amazon has it for sure the Home Depot may have it because they also have the plumbing formula. I'd scuff up the surfaces well too if you use it.

Your right about the screws, they will be fun to hind. Because they are on the bottom and i have a lip on the edge, I'm going to FG over the screws and paint the bottom panel, that should hide they from a quick glance lol. Z Thx for the props.
Made the FG panel and fiberglass-ed the enclosure walls for the sub. A few more layer, then on to body filler.

Finished FGing the remainder of the box walls. had to hot glue the curved end with small peaces of 1/4 MDF instead of kerfing a single peace of mdf. Too many curves. Also had to extend the back where the 6w3v2 magnet was, I didn't want the panel coming out 6" from the door. I just kerf a small and cover it with a cotton T shirt, and reinforced with 2 layers of FG mat. Next is to round out the top of the top MDF and make a new template to hold the 6w3 and the JL Evo comp set.

******   Forgot that where i put the Screws on the angles, I should have used Rivets with large diameter heads :( (flatter and easier to hide with paint). Will have to fix that tonight.

Are you planning on using any bracing? There is a lot of flat fiberglass in that enclosure that may flex more than you would like, especialy with that little monster in there! I am thinking a few dowels between the FG back and the MDF baffel?

I plan to fiberglass 2 1"x1" blocks in the middle of the box and then drill a 1/4 thou hole in the middle of each block for screws, this way the block act as bracing and hold the panel to the door like a spacer.
