I actually found a vendor less than 20 min away that sells 18oz mat for $7/yard
Does anyone have experience with 18oz mat? Would it be ok to use?

This is there description of it:

"18 oz, 50 inch wide Woven Roving for heavy lay-ups"

The number or weight of the mat is how much a 1' square piece of the mat and or cloth weighs.

It would be okay yes, the heavier mats absorb more resin, and aren't as flexable as the lighter weight mats. Build up is quicker as the mat is heavier. Tighter curves you need lighter weight mat or cloth. Cloth conforms better than mat. Be careful with the rovings though, a lot are sold on spools meant for chop guns. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well what exactly is a tight curve? Like would it lay well over a wheel well hump, it wouldnt matter if I cut it into managable pieces to avoid wrinkles and such. I just plan on applying this with a simple soak and brush method. Overlaying on 45* angles throughout the multiple layers

This is where im getting it from:

To me its just gonna save me time and money, in my head I see 18oz mat building up ALOT faster and could probly bang this box out in a weekend instead of a week

Something like that heavy weight mats don't conform well enough for so I used several layers of 5oz

For most sub enclosures, I use heavier mats, and you are thinking correctly 18oz will build up very quickly. But laminating is the easy not very time consuming part of the job. Waiting for things to cure properly before removing them so they don't warp all to shit is the time consuming part //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I wont ever be removing it though, it will be built in car, going up the entire side of the car all the way to the roof!!!

Ill see what they have available I guess as it local and I love that, but more than likely 18oz mat is what Im gettin I guess if it works.

Just gotta figure out how much now for those big *** sidewalls

can mat that thick hang though, like will gravity take hold and make the mat drop. Trying to think of a way to get around that, if its a problem

Get enough light weight mat to handle the sharp angles - where the wheel well arch meets the side of the car and where it goes from the horizontal plane to vertical are going to be pretty sharp angles. It's going to be tough to get the heavy mat to conform in spots like those. Biaxial cloth is fantastic for building up the flat areas.

You want to be very careful not to get air spaces between layers since they will seriously compromise the box's strength. It's a lot easier to see air bubbles if you paint the area you will be covering black before you start. Trapped air will look white.

Good tip thanks
