How can I trust the manufacture when they sell a gel-coat repair product, but show a before and after photo of an aluminum boat?

Really good gelcoat. Perfect match for my white hull. I used 16 drops of hardener with 1 oz gelcoat. Set up within 6 hrs. Was 60 degrees outside.

Very disappointed in this product. Directions are not straight forward, or even close to it. Nothing telling you how long to mix a certain sized batch, large or small. Waste of time and money don't even bother with this stuff.

This has a heavy odor wherever you store it. I first brushed this product on and was mistake. After much sanding I then rolled it on which still took a lot of sanding. This product should be sprayed but if you can't then roll it on and sand down to desired smoothness then buff it out afterwards.
