after nearly 1 week i done my foaming from kelvin
it's time to give some review here.

1stly, this thing really WORKS like a charm! (for me)
it does reduce noise significantly about 50-70 %
Kelvin told me will take 2-3 days to let all the foam fully dry and by that time will have better result,
but during the 1st day, after i finish foaming, when on the way back to office, i already feel the huge different of the noise reduce on the highway ~!

overall i must said this is a good product with a very friendly price ~ nice job Kelvin




Cheers
