fiberglass molds, parts, suppliers?

you wouldnt be using your dash as the "mold" as you say. you will use the dash or whatever part it may be to make the "mold". once the mold is made whatever part you make inside the mold will be the same size and shape as the piece you used to make the mold,(i.e. the dash or whatever piece it may happen to be)

to purchase your materials go to a local automotive paint and body supply store. not a body shop. they will have the matting, resin, gloves, masks, brushes, MEKP, sanding material, body filler, primers, styrene suppressant or anything you might need.

Well........unless im going to make a part a couple of times, i dont always make a mold. if its going to be a onetime made thing the time it takes to make the mold is too much, so i just build the piece i want. if im going to make the part numerous times then a mold is ideal because is takes longer to make the mold, but the time you save building duplicate parts is more than worth the time it took to make a mold. But, if I do make a mold and i want my finished pieces to be differrent from the original part, first you have to change the part your going to use to make the mold. make it the way you want. then make a mold of that. then you'll be able to produce multiple copies that look like the original you used to make the mold.

as far as mounting, thats pretty straight forward. metal brackets and braces can be made how ever you need them and want them to be and you can place them anywhere they need to be on the back side and just fiberglass them to the piece you made. if you rough up metal pretty well with 40 or so grit, you would not believe how well it sticks to fiberglass.

keep in mind that your first projects are not going to be the best, or maybe come out like you even imagine in your head. making things look a certain way, or how they look in pictures takes many good years of practice and developing your own tecniques and becoming comfortable with what you are doing. im not saying you cant do this or be good at it, im just saying be realistic on the first things you make and dont get discouraged. keep trying, practice, practice, and of course most importantly.....HAVE FUN. Once you become good, only your own imagination can limit you!

all the body shops where you live get their supplies and paint from somewhere. if its like here its a supply store that let them charge on their accounts and even has parts chasher delivery service. just like a parts store only for auto body supplies. go to the paint stores(not a sherwin williams) and one of them is also going to have autobody paint supplies. you can pick up things like resin and body filler from parts stores and home depot. also remember resin doesnt last forever. if it gets old it just doesnt work anymore. usually a shelf life of 90 days or so, maybe longer.

i dont know about some of the other guys, but i always use fiberglass "matting" instead of "cloth" its way stronger. you can get matting in different "weights"(thickness). i always use EVERCOAT resin. i use standard resin and finishing resin. you can buy resin already with styrene suppresant already in it or just buy it seperate and mix it into your resin.

If you can't find what you need locally, they'll ship to you.  They have some pretty good stuff, good prices too

do more research. the prices from select are absolutely ridiculous. they have cool stuff, but nothing ive never been able to get elsewhere for way cheaper. and i do mean nothing.
