Sealing a box....

Sealing a box....
Hey guys, I have a question about sealing enclosures.
Traditionally I have just siliconed the interior joints of a box.
Someone has told me that coating the inside of the MDF box with fibreglass resin helps in the sq department too.
I am inclined to test this theory. I have built 2 sealed boxes for my 2 Infinity 1030ws (I traded my 12s for 10s). The have left the back panels are off so I can seal the front of the box easier, then I will attach the rear panel and seal through the hole.
My question has to do with procedure regarding the fibreglass resin application.
Do I still silicone the joints, then resin over it? Do I only apply the resin with no silicone? Any specific resin to buy and use or is it all the same? Simply brush it on and let it dry?
Incase you haven't figured it out I have zero experience with anything to do with fibreglass or fibreglass resin.
Thanks.

Same here dude, i have no experiance with resin and fiberglass and stuff although I want to learn REALLY REALLY BAD. But to answer your question I personally don't see what the point would be to fiberglass the inside. I have not made many boxes so I am not a proffesional but I don't think it would really affect anything. MDF is pretty nonbreathable (i think?) and silicone is a great sealant so fiberglassing the inside just seems like a waste of money. That is just my thoughts though, you should prolly wait for the pros. If you do try it and ya hear a difference let me know .

I agree, The fibreglass theory only works on a Ported enclosure as far as I know, and even if it did work in sealed, it would not be audible enough to the raw human ear!! Now if this was a ported, I noticed it almost right away, so with sealed, Ima say ditch the glass Idea..save your money and buy something a little more worth your while!

Thanks for the help guys. The boxes are built, sealed and carpted (and now in the trunk )
I elected not to resin the box. I originally bought the resin but when I realised how expensive it was (relative to the rest of the box) I exchanged it for the spray glue that I needed to carpet the boxes.

If your boxes are built properly you really shouldn’t need anything to seal your joints, that’s why we use glue, and screws. The glue is the only thing you need to create a seal between the 2 pieces of wood
mdf is a porous material already it will leak a bit of air no matter what, unless your fiberglass the box. But I am going to doubt there would be an audible difference if you were to compare 2 sealed boxes one with fiberglass insides and one with out
