I've done door sill foam, wheel arch, floor panel, rear boot.
It's solely base on my personal experience and feelings so please dont ask me to prove anything.
I would say bro Kevin is a nice guy. Think he's looking for cheaper alternative for the consumers.
But there's saying 'you get what you pay for'.
I'm not saying that the product is bad/fake or Kevin is trying to con you. NO! I was well mentioned about the difference between the branded and local made.
But somehow, after the application, i have doubts. Of course do feel a difference of the car. But i could not say good or bad. You just can say 'there's difference'.
i did go back but things didnt improve.
i have to admit i consulted other shops.
But let's not compare other's products first.
Removing some Kevin's applications improve the situation.
It's not because the product is fake/bad.
That's my point.
He gave me what he said he would give me. No con case here. But might not be right for me.
Unless i know it's right, else i think i do have to pay more for the experienced and knowledgable.
And... i'm the fussy type... and this could just be an individual case.
