Working on inner and outer fenders of my 55 chevy truck. had both ready to prime. was trying to get more ready when a cat sprayed spots of both fenders. sand blasted spots yesterday but did not prime. this morning went out to find the exact out line of the spots. not rusty but visible. do you know of anything that will neutralize cat urine?

At least 1% baking soda in a water solution. Since you sand blasted, I would use a SS wire brush to scrub it good with the solution and rinse well. But that really needs to be done right after the fact, I'm not sure about urine acid, but the fumes of some acids will rust adjacent areas so watch for that.
