Touch up paint help?

[TXSunDevil]

I pulled my fenders last week and I was left with 2 rub spots down to the metal. I primed and used Toyota touch up paint. I attempted to use a toothpick but it did not work so well with the touch up paint bottle. I just used the brush. Today I attempted to wet sand both sides. The passenger side turned out acceptable. It is smooth to the touch but there is obviously some color variation. I polished it by hand with some Maguires x.20 scratch remover. It took the sanding marks out but I slightly wore down the paint along the edge while sanding. Gonna leave that.

The drivers side I am having some trouble with. Due to my brushing skills it was not smooth. I hit it with 1500 grit wet paper. I was not getting the desired result so I hit it with some wet 420. This took it down to smooth but it now showed metal underneath. It was not quite at bare metal so I cleaned it, let it dry and hit it with another coat of touch up paint. Problem is I see the same thing happening when I go to sand it again. This is what the drivers side looked like before I started sanding.

This is similar to what it looks like now. What is the best way to go about this? I am considering leaving the blob so I do not screw anything else up. Do I put clear coat over the side I am happy with? I bought some from Toyota. I am having trouble adding photos from my Mac. I can try to add others if y'all can't see the mess I am making.

White even though it's white is one of the hardest colors to match perfectly, contrary to popular belief.

I'd start by wiping the area down with a solvent and check to see how deep that scratch is. If the toothpick method doesn't work and for this it may not depending on the surface area, use a paint touch up brush and apply in thin even coats; repeating every ten minutes. I'd repeat three to four times to ensure even coverage.

Let this cure for 24 hours then wetsand with a good quality sand paper like 3M Trizact in 1500, 3000, and finally 5000 (if you have it) with a foam sanding block or D/A.

Don't push too hard as the "blob" of paint shouldn't be too much above the rest of the surrounding area. Feather the edges so there isn't an abrupt line.

Follow up with a good compound like Meguiar's 105 and then 205 and wax. Application of a clear coat shouldn't be necessary as I believe this white is a single stage paint.
