Ok here's a quick one, i have holes on my front bumper like from old fog/led lights, whats the best way to go about filling them in so they're unnoticeable?
and how can i best remove rust like from under the trunk from an old spoiler?

i need stuff i can buy at an auto shop like autozone

 

Chances are whatever you do with Autozone products is going to look like you did it...with Autozone products.

 

^^^Funny, but I used Bondo brand fiberglass repair kit to fix up a damaged front Ken bumper. It's the entire kit and can be used to fill holes, like what you speak of. The rust, well ask one of the employees for what they have work with it...

 

I'm serious. If you're not experienced enough, it's going to look like ****. It's got nothing to do with the products Autozone carries. Filling should be the easy part. Repainting/retouching would not be quite so easy.

i tried touching up a scratch on my car, it now looks like turd., i got 2 dark blobs on the side of my car

 

Touch-up paint is EVIL. They make you think you can fix it yourself but it ends up SUPER DUPER worse.
