A product I can't recommend enough is Stans No Tubes https://www.notubes.com/shop/tubeless/sealant
I have been using it on all my bikes both with tubes and without for years never had a flat and I ride everywhere I have had nails, glass shards, metal pieces in the tire but never a flat thanks to Stans.
When I received my RadRunner in June I had no Stans and it was out of stock everywhere so I was riding for months without Stans and sure enough, a flat caused by a staple.
