Mold fabric?

the term "mold fabric" just refers to the first layer of material that is applied to the project. fleece, grill cloth, trunk liner. all these are concidered mold fabric. really you can use anything that is a polyester based fabric, because it bonds well with the polyester resin. Trevor

Just keep using fleece.  Select product sells something they swear is better and im sure it is.  Wally mart fleece is good enough and cheap.

there are a lot of different places to get fleece if thats what you choose to use. i dont know if in your area you have a JoAnn Fabric, or other fabric store like that. they sell fleece and micro fleece. the down side to fleece tho is it is usually a 1 way stretch. it has a lot of stretch in 1 direction, and very little in all the others. where as with other amterials like trunk liner and grill cloth, they will stretch in all directions. there are applications where fleece does work well, but there are applications where it doesnt. there are a ton of polyester based fabrics out there......dont be afraid to try new materials. you may find something that works very well and you prefer over any thing else. it is mostly personal preference, and what you are most comfortable using.

you can make a run to the fabric store. take a look around. not much is gonna be much cheaper than grill cloth tho.

Does anyone know a place to get grille cloth for cheap?  The only place that I know of around here (Oshkosh, WI) is Radio Shack and it ain't cheap.

Grill cloth sucks because it is to thin for build up

you must be using the wrong kind.  The stuff that I used what rock hard after one dowsing of resin.  It wasn't quite as tough as using fleece but it was solid.  It was a lot smoother than working with fleece though.  Very little sanding required.  Less sanding = Good.

I dont mean that it was not hard what I do mean is it is very thin and would not be suitable for an enclosure unless you do alot of layers.  An easy way to make fleece easy to work with is to rough sand it with 40/50 grit then spray high build primer on it "Feather fill" then finish sand it.  Your done.  It actually is easier than using grill cloth.  If you want to see it in action I have some videos from Select Products that you could borrow to see the technique.  It is up to you.
