Silver Member Username: Safa19Post Number: 263 Registered: Apr-05 | i posted something not that long ago about fiberglass being as strong as mdf and the response that i got was that it wasnt and that it would have to be even thicker than the wood to almost have as much strength then how can a box like this hold 3 jl subs???  |

Silver Member Username: Safa19Post Number: 265 Registered: Apr-05 | so it will be strong enough... i got that information from people on here i had a post a little while back and forgot about it so i looked it up but it was in the archives so i couldnt add to it, i know that fiberglass isnt that strong on flat surfaces but i was told that it is strong when it has curves to it, so would fleece with polyester resin to make it hard, and body filler be enough? or should i add a layer or 2 of fiberglass mat before the body filler? o yea this is for two type R's |

Silver Member Username: Safa19Post Number: 266 Registered: Apr-05 | and licid that is just fiberglass, i have the movie that shows the steps taken to make it and there is nothing else but fleece, polyester resin, body filler, primer and the paint |

If you have a panel that's fairly flat with a lot of surface area you'll have to brace it or it will flex and produce all kinds of unwanted noise and vibration. Taking the time to get it plenty thick helps a lot to. At 1/4" it will be pretty rigid, but it will take some time too. |

Gold Member Username: Sploosh56Ohio Post Number: 1059 Registered: May-04 | yea jonathan is right. when fiberglass is jsut a flat sheet mdf is stronger but with the curves that most fiberglass boxes have it makes them extremely strong and stronger than mdf. If you're making a box out of fiber glass and some parts will be flat jsut use a piece of mdf and then coat it with some fiberglass to obtain the sleek finish that they have. |

Silver Member Username: Safa19Post Number: 267 Registered: Apr-05 | yea that is exactly what i am doing wahl, i am actually making the top, bottom, back, and sides out of mdf the only part that i am actually doing fiberglass is the side that the subs will mount to, so that i can give it some shape and give them the effect that the subs are coming out |
