Anyone have any experience with Urethane Spray Sealant Foam? Looking to finish the floor in my coupe and need to close some panel gaps and reinforcement that run along exterior panels (ie that can't be welded). The idea is stabilize and keep fumes out of the car. Thanks
Worked building aluminum boats way back, hammered rivets with plywood seats and floor boards. Expanding foam will distort aluminum and pop hammered rivets.
NNNOOOOOOOOO!!!! It is a water trap at best. So unless you want to redo all you have done, leave it alone.
10-4 on that...(welding the panels is the other way to mess them up). I understand that they make the foam with various expansion and strength rates...hoping someone could recommend one for my needs. Thanks..
i sprayed it in the wall ribbes in a van i had to help stop the booming sounds coming from the sheel metal walls. it took forever to dig it out. it has more force than than you would think, and it will hold moisture. it's great for home construction, but i won't be useing it for sealing up a car or truck again! someone said it destost aluminum and pop rivets, it'll pop factory spot welds! find something better.
please dont!!!!!I got a 51 chevy in trade that is full of this crap . and if it aint a bass boat ,corvette or a dune buggy stay away from fiberglass!! just my op
OK..foam is out..let me try again: What do you use to seal gaps between inner and outer panels and reinforcements that run along body panels. I know the factory uses it in cars...maybe they don't use the term foam...but it's flexible and will fill in the gaps. Obviously seam sealer won't work.
The factory (today) uses PVC, sprayed under high pressure, and oven cured. Not sure what they used in the old days.
I was watching the history channel when they had a special on the Chevy Volt manufacturing process. The robots were applying the stuff all over the car to seal and reduce noise, here is a link that kinda discusses the process, you can see the firewall all "sealed" (foamed?) up. http://perceptron.com/index.php/en/applications/seam-sealing.html
Eastwood has a two part sealant in a twin tube caulking gun. It mixes the two parts in the nozzle and you need a special gun they sell. It is used by the body repair industry to glue panels to cars. It won't come undone once set up. If you have a friend at a body shop, you might be able to buy the tubes and borrow the gun. RB
My (then) local NAPA loaned me the gun for free when I bought the $80+ tube-o-goo. Gun was $150 or so had I wanted to buy it. No obvious reason why it is so expensive... it's basically a proprietary-sized caulking gun.
Normally used for gaps less than 1/8". I need something strong and flexible in my old Chevy. Pulled the wood and have it framed up with steel. In the areas where I can weld to the inner body points no problem..I really would like to stabilize the exterior panels that run parallel with the steel reinforcements.
there are ALOT of foams (2-part) by 3m and other companies that are intended for auto motive use and would do exactly what you want them to do. check with your local paint supplier (stay away from home depot stuff). The 2-part foams work very well, they come in a variety of expansion rates and will not attract water. Body shops use them all the time.

There you go. If some of these guys would open their minds and maybe read a bit, they could improve the quality of their build dramatically. The key is the right product for the application.
