1. HH-66 Thinner, 1 Gallon – Prepping, Thinning, Reactivating, Cleaning, Multi-Purpose, Compatible with HH-66 Vinyl Cement – RH Adhesives
This gallon of thinner earns its place as the premier choice for bulk cleaning tasks because it serves as the essential partner to your primary adhesive. It excels at removing stubborn, unwanted residue from surfaces, rollers, and spray equipment that would otherwise be ruined by dried buildup.
I view this product as the ultimate insurance policy for anyone working with vinyl cement. It effectively reactivates hardened adhesive, which saves you from wasting expensive product when a container begins to set. However, keep in mind that its high solvent concentration necessitates a well-ventilated workspace to ensure safety during use.
Users frequently note that this thinner is indispensable for maintaining equipment longevity.
Buyers appreciate that the colorless formula leaves no unsightly residue behind on finished projects.
The primary feedback confirms it is a necessary purchase for anyone who uses HH-66 cement in larger quantities.

2. RH Adhesives Vinyl Patch Kit with 10" x 10" Reinforced Flexible PVC, 1 oz. Tube of HH-66 TF Vinyl Cement, Applicator Brush, Alcohol Wipes (White, Heavyweight PVC (22 oz.))
This kit is tailored for the DIY repair enthusiast who needs a reliable, all-in-one fix for tears or punctures. It provides everything from the reinforced PVC patch to the alcohol wipes, making it the most practical option for immediate, small-scale damage control.
In my view, this is the most valuable package for those who do not want to hunt for individual supplies. The inclusion of toluene-free cement is a thoughtful touch for those sensitive to harsh chemicals, and the ability to bond materials even while submerged in water is a major technical advantage. I find this kit to be the most efficient way to handle sudden accidents without needing to source separate materials.
Reviewers consistently report that the patch material is exceptionally sturdy and holds up well under tension.
Many find the inclusion of pre-cut, reinforced vinyl saves significant time during the repair process.
Buyers emphasize that the adhesive remains flexible, preventing the repair site from becoming brittle or prone to cracking.

Choosing Between Them
I recommend the RH Adhesives Vinyl Patch Kit as the primary choice for most people because it offers a ready to use, comprehensive set for quick fixes. If you are managing ongoing maintenance or large-scale manufacturing, the HH-66 Thinner is the necessary companion for cleanup and solvent control.
While these products are highly effective, remember that all solvent-based adhesives require careful handling. Always ensure you are working in a space with proper airflow to manage fumes effectively, as this is the most consistent safety feedback I encountered across all buyer discussions.
