This thread will show how my Trimagnum body was built. While this might seem off topic since the materials and methods are related it should help.
The foam is Tuff-R 1" foam from Home Depot the upside is price and ease of purchase . The downside it's coated on both sides one side a paper backed foil the other is a blue plastic with foil glued to the foam.
The paper backed side is easy to remove the foil side fights you but it does come off.
The contact cement idea was ditched in favor of Gorrilla glue please remember this was used on my body and worked for me. As it sets it foams and that foam sands well .To hold the panels in place bamboo sticks were used while it dried.
Contact cement needs to dry until it is just mildly tacky then the parts put together. While it does bond well it doesn't allow for adjustment once it's stuck it's STUCK.
The Tuff-R sands and shapes well it does however have long fiberglass strands in it so gloves are nice. The powder has a high grit factor so it will bother your skin some.
Great stuff foam in a can may be used to fill cracks and gaps in panels. Using it to build whole parts should be avoided as it doesn't have the density foam sheet has.
Polyester resin was used because of the price advantage . Epoxy is safer low oder and stronger but at nearly double the price of Poly. Any 2 part system will be affected by heat so follow the temperature guidelines closely. If you are just bound and determined to work in cold weather heat lamps can be used. But it's not very safe and while it worked for me I wouldn't do it again .
So there is some first hand advice it's not the only way to do it . It may not be the best method for everyone but it did result in a completed and running vehicle .
the ad must be bootstrapped to the YouTube video if it poses a problem the video will be deleted.
