How do you know if you should be using chop mat or cloth?? Is one for curves and one for flat?? Does one have more structual properties than the other???

neither are best in a flat application...when doing something flat use wood as glass is strogest around curves.

true about the flat surface. but in general use, use mat over cloth.

I think its personal preference. I always used mat, because I felt it was much thicker, so you had to do less layers. But whatever floats your boat.

And x2 on what Dre said.

to me, cloth always seemed to be thicker and require less layering

When I fiberglass, I use cut hair from an Italian barber shop.

I use cloth. As long as you're using a decent weight, it won't matter mat or cloth. Mat is just a pain in the *** as far as I'm concerned. Messy as hell.

Holy hell. I've gotten 20oz, and it was hard to work with around bends... but man that stuff is sturdy. Takes a hellofalot of resin to impregnate.

I use matte, since the random direction and thickness over cloth seems to work better for strength, however this is just the home depot stuff.

Cloth does finish better, so I like to use it for the last layer.

If you can find a dense cloth use it. If you are getting the walmart or home depot or lowes stuff get mat

Mat = quicker build up as mat is usually sold in heavier weights than cloth. Cloth tends to conform better to the tighter curves. If you plan on building enclosures with it. I would look into some of the heavier biaxial mats ( biaxial mats are heavy arse roving with lighter weight mat stitched to it ) it's more expensive per yard. But you actually end up saving money in the end because you use less. There used to be a picture I made floating around on this forum of a car parked on top of an enclosure I made with 4 layers of of 20oz kyntex biaxial mat. The chit is strong . Also if your laying mat on the outside of your enclosure , a layer of cloth for the final layer tends to make finishing a little easier. :)
