Answer:
If the quality did not match the sample then Sonny can sue. But Sonny must demonstrate that the sample provided was the basis of the bargain.
Explanation:
In order to demonstrate this Sonny need to show the court the exact contractual agreement that he made with the supplier of the paint. The proof will be stronger if sonny had a signature of the supplier within the agreement (not just verbal),
It would be even better if Sony can provide proof that the actual goods that he got is not working as intended (maybe by showing the ingredients in the product or by some sort of experiment that documented through videos)
When the court agree with Sony's Claim, the supplier will be required to either provide Sony with new products as agreed upon, or give sony complete refund with additional fine for the damages that might occurred because of the false products
