I was told to do some fiberglass work in my car, and to use rope to strengthen it. Specifically the rear deck, I need to seal it and stiffen it up.
Does anyone have any pics or a how to on using rope in this application? what kind of rope? what size? how to apply it?
anything you guys can offer would be good. Im going to put up some pics of "so far" when I get home tonite.
thanks!
I'll be paying attention on this one.. i've never heard of using such a thing..

yeah. you fiberglass rope to the inside of a larger progress. like your sub box for instance Jared. after that you lay fiberglass mat over that. it adds a LOT ov strength to bigger projects
honestly, you would be better off using steel mesh, like what they use to make window screens, because, its super thin, can go in between layers and will be alot easier to work with, not to mention it will provide uniform strength and it will save you a bit of time.

not what they are talking abuot. the rope is just laid in wet resin. It is like an S shape and then resined over. I dont have any pics but thats the principal behind it. The rope will absorb the resin and make it super strong.
let me see if i can dig up a pic. i use thick rope in my larger pieces that need good strength. its more of an extra precaution. i usually lay 7-9 layers of glass on big pieces. the rope just aids in the support.
here you can see 2 of the rope pieces. theres 6 all together if i remember correctly
Having the rope adds strength to the flat surface.
Resin and glass is weak on flat surfaces, but very strong when curved.
The rope being cylindrical, once absorbed with polyester resin becomes very strong, once you take the rope and curve it around the rear deck, its gonna stiffen it up alot. Then throw some chopped mat or fiberglass cloth down over the top directly to the rear deck

do yourself a favor aswell. go to an auto part store and buy a gallon right off the bat, you will pay a little more, but still cheaper than buying individual quarts from walmart.
Search around aswell, a gallon should cost you around $32-35.

aaahhhh, i see you use the rope as a kind of flexible skeleton.... i thought he wanted to run it s shaped all over......lol but i would still throw the screen in just for added strength.

The point is that it wont be flexible.
He wants to run it back and fourth.

ahh I see now wojo, I see how easy used it I have pics when my box was being built he just used a mat and used resin on top of that. I see how this could strengthen up some of the bigger projects. Thanks for those pics Easy.. Learned a little something.

Hey thanks for the tips guys, I started today, I covered my deck in 2 layers and ran out, I started with the inside of my enclosure, and a bit of work around it to seal the trunk up. Im gonna do the rope and more resin tommorrow, then ill start with actually making it look pretty.
Alex, thanks for the tip, just closing off the deck a little and the trunk from the cabin, everything just a little bit, minus the sides under the window the subs got a bit louder. Im liking this more and more

From the looks of that picture and color of the resin. He used too much resin, and not enough mat/cloth. Maybe its an optical illusion, but resin is brittle by itself aswell. You dont want to use more resin than your cloth or mat can soak up. You will always have some left over, and thats ok, but that looks like an extra gallon was just poured all over.
Still looks good none the less.

IIRC he used foil underneath. so the amount of color might be due to that.
