thanks for all the advice guys. below is what i posted in my build thread. one day when i have more time i will give the other methods a try.
made some progress on the trunk. i decided to use mdf since i have all the tools and somewhat know what im doing. so far the pieces around the latch are 1/2 and the uprights are all 5/8". both are ultralight mdf with the 1/2" at 42lbs per sheet and the 5/8" at 52lbs (3/4 regular is ~96lbs). the side pieces you see now have the inlaid portion cut out, but there is still more to cut. they currently weigh ~1.2lbs. im using 1/8" mdf for the inlay and should have these panels under 2 lbs. i know i could have saved some more weight with foam, but it would have been a lot more time and money and im not sure i would have gained that much. i will end up routing a portion of the bottom piece out to save weight as well.
i talked to the local shop and they want $75 an hour and $450 a hide to cover. ive looked around online and found hides around $150 shipped. ive already recieved some samples and they look really good (although not sure what im looking for). i plan on getting one and covering the trunk myself. i might do the rear shelf as well, but i have a feeling the door panels, dash and center console will be left to the pros.
i'll post more pics later.
