Fiberglassing the inside of a box.

[Basshead08]

When you guys fiberglass the inside of a box for strength do you fiberglass the entire inside of the box or just the joints and corners?

I just do joints and corners. I also do a 50/50 mix bondo and glass resin.

whole box.

i brush the whole box thru the inside and let it harden....

i you have a ported box put ALOT of resin in it brush resin in the inside and especially the inside this way the air will flow smoothly thru.

not only that but your box wont leak for shizz

well you said for STRENGTH....so you want to add some mat or cloth to that resin...resin alone will add no strength...itll seal the box up and make it airtight...but wont strengthen anything. the threads or weave in fiberglass mat or cloth is what adds strength, not plain resin.

Yea I'm talking glass and resin. Looking to make my new box as strong as possible.

What I do, is 1 layer resin.... harden.... cut cloth peices to size of sides top bottem and baffles,... then add resin put cloth on and call it done. but there is no such thing as too strong (for boxes)
