Two days ago, I applied Rust-oleum Epoxy Shield Clear Coat over the previously done epoxy paint on my garage floor. Half blinded by the fumes and dripping sweat, I missed about four spots of 1 sq. ft. each. I want to touch up those areas without having to buy another $90 clear coat kit from Rust-oleum. I tried using their spray-on Crystal Clear Enamel, but after four coats, the results were uneven and blotchy in terms of the gloss. I would like to find a can (preferably quart-size or smaller) of high gloss clear coat which I could apply with a brush or roller. Although the areas are not located where the cars' tires will often roll over them, the coating still needs to be hard and waterproof as there will be drips of water and salt sludge this winter. Protection from fading due to UV rays would be a plus. Any suggestions?

 

It's next to impossible to touch up coatings on a floor. Since you've sealed the missed spots, I'd leave it as is and try to do better next time after this application has worn down.
