Fabricating trunk mold

Hey guys.

I am a newbie to the forum. In the past few months I have been preparing my first ever fiberglass project. I plan on creating a fiberglass mold for my whole car trunk. I want to mainly replace the carpeting with the mold. I have been preparing the trunk by taping all the carpet. I have purchased the resin already and this week I plan on covering everything with aluminum foil and beginning to apply the resin onto the foil to make the shape.

I have seen people post on the forum about using wax as a release agent. My question is, is this really necessary? If I pull off the aluminum foil won't the fiberglass come out of the trunk too since the resin won't penetrate to the masking tape?

Also, do you think it would be easier to remove the trunk lining from the car before applying the resin?

Thanks.

good luck man. be sure your tape sets down flat, you can use a big dry sponge to flatten the foil as well. the reason some people use mold release wax is they dont like the tape and foil sticking to the back of their F/G creations. its the back! no one sees it but the installers! you may have to tug a little harder to get the piece out but there is no reason you have to use mold release wax for somethign liek this.

if this is your first try @ F/G i recomend somethign a little smaller than a full trunk mold for your first porject. as with any trade, there is a learnign curve and you dont want to waste $100's on silly newbie mistakes. you might try building a box for a single 10" sub or something and sell it if it turns out well but it will get you comfotrable with fiberglass. just an idea? good luck and post pics!
