Btw, shops will never “grind off” a tinted color, they’ll scuff and respray.[/QUOTE]

In conjunction with tungsten carbide bits. Preps real quick and bevels area to be repaired. Never used a Home Depot quality one.
Never an abrasive wheel. Call it grinding, call it scuffing, call it prep. Removal of material in preparation for wet gel coat.
Didn't say it impossible, said its not easy. Im no expert but from your pic scratch looks like it's above far right 2 scews in rub rail, just below step line in glass. Only thing I can see that's not perfect. You nailed a lot of the big ones in your points. Also catalyst mixing ratios are pretty clutch, especially since it could cause a fire if mixed too "hot"
Said we are fortunate to have a very qualified pro in our area. Some aren't as fortunate. Necessity breeds invention so have at it.
Buy a quart, kick some off with catalyst and sand away.

Absolutely true about a fire! As a 18 year old kid, I was using a disposable paper bucket for mixing, and it burst into flames. It’s a funny story now, 30 years later. A more common problem is a porous cure if mixed to heavy with catalyst. If you can read a measuring cup it is not a problem, I was just stupid.

Bakes5, I will ask my vendor who they suggest for a retail supplier.

I was told a good source is Composite One in Goshen Indiana.
