[QUOTE=NSboatman;3664016]Ppg/ameron products are excellent for this. I’ve used the amerlock system in our water
tank specifically; but usually use a system on the exterior that starts with Ameron 240 high build followed by Amershield LPU on top. At least 2 coats of each, sprayed or rolled and tipped. Tough and extremely reliable.
, I have decanted the gallon cans into mason jars and used a little co2 to displace air when sealing. Works well- and I’ve had stuff last years this way.
A few paint
bush strokes over some scratches & blisters
exposing bare steel
. The coating needed would be minimum. I thought there would be a product for example even an epoxy paste to cover, over which would be my bottom ablative Epoxy Cop. To answer your question ... 3 - 4 yrs would be ball park. Thanks again...
