FoamSeal and other 2-part expanded urethanes are "closed-cell" formulations...No voids available to hold moisture. So it's also GREAT in preventing rust from forming in chassis-rails etc. as well as being an excellent "sound deadening" material to kill "Noise, Vibration and Harshness"... IMHO, win...Win...WIN!sigma-turbo wrote:I just look at that and it screams I HOLD MOISTURE
Both...High-end cars like Mercedes-Benz have used it for quite awhile. Other "high-end" cars (like the Evo 7 and other newer Lancers :lol: ) have also used it for years.cinco wrote:is this for a track car or a street car?
It's a 2-part mix that's poured/pumped into cavity and expands to fill the space.cinco wrote:...sprayed expanding foam into the holes...

Seems I was wrong. (~ Depending on the chassis design) Foamseal can increase chassis stiffness up to 300% :!: ...
Though it may not be advisable to go that high for street use.
While structural foam, in "2 lb/cub ft" density can stiffen chassis members up to 40 percent;
maybe a combination of densities can be used for even better results.
Use "2 lb/cub ft" density in chassis rails to allow a greater level of "give" in side impacts
(to reduce the force actually transferred to the occupants.)
... but use even higher densities for the "skinny" "A" (windscreen) and "B" (door) pillars
that usually collapse, or even worse... "tear" so easily in an accident.
Reduced roof and side pillar collapse... plus better seats and belts... plus OEM "air bags" to
absorb forces generated during accidents, should be a much better life-saving
combination than 3-point seat-belts, air-bags and plastic trim alone.
:idea: There's your roll-cage :idea: ... with no dangerous intrusive bars at all;
(and no padding needed) reducing the need for door and floor bars
... with the added benefit of being lighter than a cage for :idea: improved acceleration :idea: ...
(Cheaper and less work.) Have your cake... and eat it too!
A local "weld-in" full cage is $14-16,000 installed. :shock:
Humm... maybe I should have an "Evo 6 roll cage" sale now! :lol:
