hello, was wondering what is the period for this promotion?

hello,did the foaming today,now am waiting for the whole thing to be properly finished and will give my review

yeah let it cure for a day already and i can say that the noise from the road has lessen, and handling feels better while the car feels more solid but like some other says,to the material to be fully cured will take more time so will include if there is more difference..

alright so a week has gone by, for me, the effect of the foaming was most noticeable regarding the feeling of the car, feeling more solid on the 2nd day.. but with a stock blm, the noise pollution were coming from all over the place so i cant differentiate the before and after noise reduction from the foaming alone.. i do think the road noise has lessen but to what extent i cant say..all in all, for what i got, it was worth it

now ive done some diy sound proofing on the bonnet, engine bay, front doors and spare tyre compartment,i think 70% of the noise i had before are gone ) the nagging noise i get now are from the wind and tire..if i do the a pillar,would the wind noise be lowered?
