Thanks Ducknut!
I'm not able to scratch it off. I should have said I did the sideways finger nail test and I could make a mark, althought I painted it at 8pm last night and tested it a 7am today. I'm just worried about dropping stuff and having scratches everywhere. I will use the boat 95% of the time for fishing, so I'm not sure if I should continue with the plan. I read that people use Brownells clear matt on guns to protect the krylon camo paint. I think it not being a gloss finish makes it less scratch resistant. It also seams that it is very pourous and would stain. I might just go with a regular paint job. I did just buy and paint the test piece with krylon clear matt. We will see how that works. The brownells is epoxy based.
