Just to add my two cents, how can you rectify this problem, especially if water has already started accumulating inside the chassis holes & places that we cannot see?

No worries. Due to newer car, we do not prey open the plastic cover that cover up the chassis hole (only available on some car model like forte and they usually fall off after a year to unknown reason).

Sounds like the sentence a lazy man will use to avoid doing a proper and through job...

Really? So how about holes that are not covered which are at the top, and the connecting chassis holes are at the bottom (foamed)... I'm sure the laws of gravity applies in this case.
How can water come out from the top again... Unless you have a Batcave and can rotate the car 180 degrees to drain the water.

Chassis with holes are not a problem because somehow or rather, the water will trickle down to the bottom, and the holes will allow air to enter and dry the water out at high speeds.
Furthermore, when a car moves, eventhough it generates heat, there's a lot of cold spots, and also hot spots... I honestly don't believe all the foamed areas are hot enough all the time to let the water evapourate.
Also, it's rainy season now. If there's chance of water entering the chassis & collecting there each day, this will cause problems in long run, even if it's coated with anti-rust, etc.
All the car manufacturers do no guarantee rust-proof for more than 5 years.

Manufacturers who don't put anti-rust on the undercarriage, that's another topic. And furthermore, you should know better than the customer instead of us advising you on how to do your job.
After all, we're paying for you to take care of our car when using your product & also to advise us all the pros and cons of your product.

You have a very good technique of diverting away the topic and not answering my technical questions regarding your product.
From what I can see, you cannot guarantee your foaming will not let water collect in the chassis area after it's applied and blocks all the normal exit points from allowing water, especially during rain to flow out naturally.

I dully accept IceCube previous explaination that I don't feel the difference because I just bought the car. I accept that until yesterday I gave Desmond a visit at KLAuto (the infamous? shop at Jln Ipoh).

Since I was there anyway, I take the chance to have Desmond and the team to inspect the car chassis, and to my surprised, the foam was not fully done to extend to some section (I remember bro Arj he went back to Kevin's to rectify some missing section too). Many sections are left empty! This is a blessing in disguise as well since I can then still have the chance for Desmond team to inject their AutoFoam (which is expensive, yes). I was skeptical but then I can really feel the difference after that! It was correctly done!

Chassis foaming, if performed correctly, would yield significant results even after a few hours. You can really feel the difference. There's no need to struggle to 'feel' it and eventually you'll fall for a placebo effect to justify your spending.

I feel so dissapointed, should just pay more and do it right the first time at KLAuto. About the foam quality, no i don't feel it's the same. I checked on a 6 year old+ AutoFoam-ed Subaru, with my recently put EA foam, it's different. But then this has been debated by many people here and the other thread, I rest my case. Use your judgement. Many has been said by many people already. I'm just a silly guy who bought my first car. What do I know right.

I'm sorry Kevin, you guys seems like a bunch of honest guy. This is just my honest 2 cent opinion and experience. I hope I will not get into trouble for writing a negative review but I think many needs to be warned just in case someone face the same issue.

Do I seriously need to remind you on where I'm coming from with my questions on your in-complete foaming? I am asking why you're so lazy to foam the entire undercarriage instead of leaving holes / gaps in the undercarriage chassis which allows for water to enter into the missing sections (and your incomplete foam will block flow of the water that enters through this spots). Furthermore, after reading back some of your customers comments, seems that your foam quality has issues. It doesn't really seem to improve the handling and performance as KL Auto does. I guess more sensitive drivers would only be able to feel this. Lastly, starting discussions with 'thanks for the bump' seems to imply you don't welcome negative comments / questions that you cannot answer properly.

From what I read from the last 2 messages, we need to lower our expectations on the product? From what was advertised, the product promised to improve handling & reduce NVH.
Now end-users are claiming we have to lower expectations (win some, lose some) to get better handling but a noisier car? Seems like false advertising...

Furthermore, why does a person need to pay more for additional soundproofing when the foam is expected to reduce noise levels, although not by much, because the seller is unable to ensure all areas of the chassis is foamed completely & correctly?
