hi everyone. my first post here. heh

im in need of some good advice from you all. i layed the first and second layers of glass over my enclosure, but i did a terrible job i think. i have strands of fg sticking up all over the place, and theyve basically hardened with resin. now i can't lay any additional glass on top of the first two because any additional layers wont sit flat because those strands are preventing it. :crap: im kind of bummed out as the project was looking really good up until now.

what should i do? i was thinking i could just use a palm sander to even the surface and rid those strands of fg that are sticking up. good idea? or no?

here's what my project looks like by the way.. before the glassing that is...

Wait..
there isn't any resin applied in the second picture is there? I sugguest taking a paintbrush and making sure that you get a nice even saturation of the material. After you resin your cloth, then do a couple layers of fiberglass mat, as you need some strength being it is a subwoofer enclosure.

He stated that is BEFORE he glassed it.

Now he has uneven glass...

I can not help this, as I have never worked with fiber glass, just trying to clarify the situation ;)

Yeah you did a great job stretching it over your frame. Nice job on the frame too, should turn out great depending on how the resin and mat works out for you. Could you post a picture of the problem you are seeking help with?

Yeah that could be a good idea to get back to a flat even surface.. post a picture though for best advice.

^ thanks for the ups on the fleecing

also.. nope.. no resin applied in that light blue pic. i soaked the fleece with resin with no problems like shrinking or wrinkling. it came out really good. my problem now are the strands that are making the surface very uneven. i sort of got the hang of laying down the glass after i had arready screwed up one side.. hehe... but now im left with one good flat even side suitable for more fg layers and the other side being terrible with strands poking up all over the place! haha. im thinking the palm sander idea will work... any thoughts? it seems like a logical solution...
btw.. thanks for the replies so far. :cool:

ok, did you resin the fleece, or did you lay fiberglass over the fleece?

edit, n/m he posted right before I posted

you got alot of good advice here so far. Basically you can keep going ahead wih what you are doing, adding more layers. You can sand that with an orbital sander and die grinder to get the most of the high spots down, then you can smooth it all out by mixing some body filler and resin together. pour it all over the enclosure. Making sure that it is also propped off of the work table so that it doesnt end up sticking. The "body shake" allows you to get a smooth surface by filling in the low parts. It basically adds another reinforcing layer that you can pour on. YOu will have to sand that smooth, and add some bondo here and there. All depending on how you plan on finishing it. If you paint it, it needs to be flawless. If you are going to atempt to stretch carpet it needs to be just fairly smooth with no noticeable divets. Keep going you are on the right track. ( I hope you got really good saturation between the fleece and the rings.) Get us some more pics soon.

Cut the strands that are sticking up, sand in between layers.

yea just trim down the pointy stuff and be on your way. If you use a chip brush to glass the mat it will help out a lot in keeping it all smooth.

( apply the glass to the inside of the enclosure next time :) )

^^^ that's the way I try to do everything. Leave the back for the last panel so I can glass from the inside. But too late for that now. Just sand, grind, cut , gnaw :D Do what you have to do, to remove the high spots and straggling strands of mat. A fglass roller is one of the greatest and most under used tools known to man kind :)

so that you don't get them strands sticking up next time.

get a paint brush, and cut the brush so its only 1" long. then DRENCH it in resin, the more resin over them little peices, it will be hard for a strand to stick up. so if its got a bit "more" resin on the strand it will sink :) esp with a stiff brush, dab the resin on the fiberglass mat...

nice fleecing btw

hint* Buy a roller *hint You will wonder why you didn't get it sooner. :)

updated with just more pics. thanks to all who threw some advice out to me. there's definately a learning curve with glassing.. and i feel pretty comfortable working with it now.. :cool: im done with the glassing part.. now im just throwing body filler on it. here are the pics though...

What is this going in? Good job by the way, and Welcome to CA.com!

The seats look like Rang Rover, but the lights don't

have fun sanding that 0_o

i usually try to lay all my resin\matt down on the inside if i can, but if i cant - i do it all at once, 5 layers right then and there. that way i dont have to do any sanding between layers, and it takes less resin (because it soaks through everything).

but yes, it looks nice but i would have prolly mounted the amp to the enclosure somehow. :p:

hey I think it looks pretty good for trying something new. But the best way on your next one is to put the glass on the inside. Ive even seen people just coat the inside with resin and aerofil mix.

hey thanks for the compliments. yea... i wanted to glass from the inside.. but the baffles are only so large... 10s are going into these... and i think it wouldve been difficult to do the middle curved area. im sanding it right now... its gonna take me some time to get the little bumps out... :(

also.. this is going into a scion tc.. heh

AND.. hehe.. that amp isnt in its permanent location.. just a temp setup so i have some bass in the ride to work. but if you look closely.. the top of the enclosure isnt flush with the seats. the enclosure is going to be lifted about 3" by a false floor and the amp is going to be underneath visible through some plexi. at the rate this sanding part of the project is going at, the floor wont come into the picture for about another 2 weeks.. :uhoh:

The main reason for laying multiple layers at once is heat. More heat builds up with multiple layers, this helps the glass to cure properly. :)
