RE: Another large scale Impreza project
aluminiun is a real ******* to glue unless you use something like a sikaflex type adhesive, the problem is those products take days to cure, the curing time is a ******* but we use it at work for building truck bodies (in combination with rivets).
Bolts are always a good bet for fixings with aly just remember to put washers under the nut and bolt head to prevent chafing, rivets are good but tend to stretch and loosen over time with any stress
