My .02
Well worth the work IMO.
This is not really a one weekend project unless you like to burn the midnight oil. This is best done with plenty of time to do it right and probably best done in summer since the materials are more pliable in higher temps.
eDead is hands down the best IMO, sticks well and is very durable. Spend the extra $ on the thicker variety. The pourable stuff for the floorpans is very effective, although it is costly.
On a budget (like I was) Fatmat works well if you double it up on the floorpan, and mine is still in place after a couple years of long, hard trails. I have had no problems with Fatmat sticking.
All sound deadening materials reek to high heaven because of their composition and the adhesive... this smell will go away. My truck smelled like a CALTRANS tar truck inside for about a month but is now odor free
Preparation is critical. I cleaned out the truck with soap an water, dried it well, and then I wiped down ALL surfaces with alcohol to remove oil, residue, etc. You dont want your materials to not stick!
Dont cut corners, if you're going to disassemble the interior, pull it all out - seats, carpet, door panels, etc. This is a good time for oddball maintenance, lubrication in doors, and overall inspection.
Catalog your parts as you remove them and have a safe place to store them inside. Ziplock bags, tape, and a sharpie for marking and keeping them together will pay off at reassembly time!
Take care with plastic parts since they may be brittle on an 85 4Runner (I had an 88 4Runner and they were a little brittle) and I'm sure they are hard to replace. You can get good automotive interior spray paint that is for dash and door panels that you could use to freshen up the appearance of any defects. I'd just do them all for a brand new look
When you apply your materials, use the roller and put your back into it! Make it adhere well. Cut small strips vice large ones and piece it together like a puzzle. This will allow you to get it in tight door spaces etc. Be aware of functionality of systems - dont get it in the way of window travel etc.
The devil
is in the details, but take your time and have fun!
If you need any help shoot me a PM.
