HOOD 1.JPG
I watched a couple videos on Youtube on how to fix nicks in the paint that had rust in them. I'm referring to the little nicks caused by little pebbles or whatever that hit the hood. I had many little nicks in my hood that had rusted so I ground out the rust with a dremel tool and then built up each nick with a little brush with multiple coats of etching primer followed by multiple coats of "matching" paint. The problem is that the metallic silver paint (Toyota Sienna 1D7 Silver Shadow Pearl) doesn't mix well like it does if sprayed so I'm not sure how well it will match when I sand it smooth.

The paint is built up pretty high where the nicks were and is outside the perimeter of the original nicks Aaargh! I know I created a lot more work for myself!

QUESTIONS FOR THE EXPERTS, PLEASE...

1) Any suggestions on how I can sand these ridiculous "touched up" areas smooth in a way that won't damage the surrounding paint?

2) Or is it hopeless to think I can sand the "touched up" areas smooth without damaging the surrounding paint and instead I should just sand the entire hood smooth and repaint it?

Thanks!

I mean, if you just want the piles of paint off there without further damaging the surrounding paint get some lacquer thinner and I'm sure that "touch-up" paint will wipe right off. As to the "root" of the problem here..... Metallic silver is one of the absolute worst types of color/paint to try and do this way. And, geez, look how many spots you have. It becomes a "connect the dots" type look with the human eye always drawn to irregularity when seeing the panel. The whole hood needs redone and then blended as well....if it's a daily driver it might just be cheaper to search for a silver one in better shape from www.car-parts.com

I did search for a better silver one and wasted the bulk of a day because the junkyard owner lied repeatedly about the condition of the hood when I called. He said it was "A+ insurance grade" which according to him meant no dents, no scratches, no rust and the paint is perfect. I drove 1.5 hours to see it and had to wait around another hour and when I finally saw it it had huge scratches. When I went back to his office to ask why he lied to me he said "everyone knows insurance grade means it will need new paint." He knew I had a long drive ahead of me too.

I get it, however, if you don't have a lot of painting experience you are about to jump down an even worse rabbit hole with a silver like this.... Maybe try and find a local garage/semi-pro paint guy locally. In my old neighborhood I was that guy. We all used to trade favors back in forth for various skilled stuff.

Paint is beyond touch up. Needs a repaint.

Agree. Might have got away with it before the Dremel "sanding" but unlikely now. Try the suggestion above, first, to remove the excess paint with thinners and see how it looks, but I doubt your chances of success.

I used a pointy little bit on the Dremel to knock out the rust in the nicks. I have thought about this and I really think what screwed it up was that the matching silver paint looked like crap when I put drops of it into the nicks with a small brush because it doesn't mix when you do that. The same paint looks great sprayed out of the can but it doesn't mix well when you spray some into the cap and brush it on. I know this paint looks great when sprayed because I touched up some areas on the bumper that are difficult to tell that I did the touch up.

So just to illustrate this point.... House paint- I brush it, roll it, and spray it. It will all look different even on the same surface. In house painting we don't really care about that a whole lot as we are working with solid colors and well, it ain't a car! Even though they call stuff like you have there "touch-up paint" it will always work the best sprayed as this lays the metallic down more like the OEM coating. When I'm doing furniture touch-up I can get by with using artists brushes with touch-up colors because I want to emulate grain irregularities and even then I'm still spraying over and blending as needed.
Bottom line.....hood needs repaint.....

Any time a "drop" of a metallic paint is applied to a surface the metallic will
separate a little causing it to be a different color.
Metallics have to be applied in thin enough layers to keep it from doing that,
and spraying is the easiest way to get it to set up before the metallics can move of float.
If you have to use a touch up paint with a brush, it has to be done with very light
coats that can dry fast so it can hold.
It takes a lot of thin coats, but even then it won't look perfect.
