Mountain bikes are bound to get damaged. That’s a fact of life. You can always sandblast and powder coat once the bike is thrashed (if aluminum) but the quicker you give up on keeping it perfect, the more of your sanity remains. I don’t deal with invisiframe either, waste of money in my opinion...
My bike is 7 months old, I would need a gallon of paint to touch up all the scratches,,,,, granite is hard on painted frames. I’m actually digging it. I figured in a year to strip it and powder coat. For now it’s battle scars.
