Nice patina???!!! Someone watches Antiques Road Show...A LOT!!! :rofl I do agree that yellow is a very visible color and likely stay bright even after a bit of "aging"...! I have used Nelson Rigg, Dry Rider and others...the key being sealed seams...if not sealed, get some flexible RTV sealer as used in tent repair of nylon fabrics and apply to intersections...crotch and both inner thigh areas. Nothing worse than sitting in a puddle of water...
. Also spraying 3M Scotchgard can water proof areas that get show seepage.
