I have an old Morgan Spa that has some hair line cracks on the inside step. I am told I need to use a product specifically for acrylic repair.
What is the best thing to use? I just rebuilt the cabinet as well as replumbed w/ new jets and a manifold plumbing set-up so I weat to do a nice job, without spending a million bucks.
Thanks

I leave'em alone. Keep the spa covered when not in use. The sun is the biggest enemy for these things.
