I don't know about coatings for your stainless, but I suspect no. They fracture at welds from shifting, and in respect to your Westsail tanks, from a lower-grade weld bead and the resultant galvanic corrosion
. Also, bleach added to water
tanks to prevent algae buildup will cause will cause localized, pin-hole corrosion in your stainless tanks, especially on the underside. Often Westsail set the tanks in the bilge
without spacers, allowing debris to fill any voids and create an anoxic environment
, perfect for ruining your tank.
One thing I DO NOT suggest is trying to put fiberglass
on the outside of your stainless tank; the previous owner of our W32 tried this, but it failed due to SS's gassing, and the already present galvanic pinholes. We replaced our tanks with a single
plastic tank (supplied by Bud Taplin.)
Our stainless tanks as I was pulling them out - the yellow skin is the previous owner's attempted repair with a layer of epoxy
The sludge under our tanks due to pockets for debris to fill:

MarkJ, you're right - stainless is a great metal, but those expensive scalpels would deteriorate pretty quick in a puddle of bilge
water, regularly covered in stagnant, Chloride-rich water.
Good luck Chris,
