No they are not. You’ve probably seen the kits with little jars of colored paste or little bottles of colorant that you have to mix together. While these kinds of products may work for some very minor damage, based on our 45 years of leather and vinyl repair experience, we’re skeptical that they will provide you with a long lasting, invisible repair as claimed. We’ve tested a few and let’s just say our results were much less satisfactory than what was advertised.
There are solvent based products available but those are meant strictly for vinyl repair. Solvent based products are not suitable for leather. However, water based products are suitable for leather and vinyl.
Professionals use products like ours that are water based. Quality repairs require a two step process of using a professional repair compound and a top color coat. Repairs may also require a sub-patch material to strengthen the repair; our kit includes this material. With our Color Flex you have the ability to blend the color into the surrounding area, in the event that the color doesn’t match perfectly. You can’t do that with those little jars of colored paste.
