Note about seam seal kits.
For most applications the #362 Seam Grip Kit is easier to use. Seam Grip is thin enough to soak into stitching and work with the syringe without thinner. It's faster and easier to use than the thicker Aqua Seal (#309) which requires thinning to work with the syringe. On the other hand, the Aqua Seal is a much better adhesive.
