Quick easy way to touch up scratches and rust

[DVad3r]

I have rust spots on my car and also some scratches mostly on the plastic bumper bits, mainly from being swiped by other cars. I want to patch these things up, get rid of the rust so no more spreads. I don't care about making it look super good, I just want a practical fix. This car is on its way out and won't be going to any car shows?

What's the best way to do this?

You will have to clean off the rust completely and seal the bare metal that is then exposed from moisture with a decent primer. then depending on the area and desires; touch-up paint or spray paint (can or gun) the area.

Plastic bumper - touch-up paint unless you want to try to fill in the scratch with some type of compound (I do not know what should be used - check with a auto store/body shop)

Small, superficial scratches can be filled in pretty well with touch-up paint. I recommend using a toothpick because it's much neater than using the brush that comes in the bottle.

For larger/deeper scratches, the proper way to re-paint is to sand that entire area down and re-paint the whole panel. Using touch-up paint is not recommended.

For rust, you definitely have to sand off all the rust. If you don't, the paint you put on top of it won't last.

The whole sand, prime, paint, clear is for cars you care about. For the rest a rust neutralizer works just fine.

Scuff marks on plastic bumpers is usually a mix of paint off the other car and scrapes down past your paint and onto the plastic underneath. You can easily remove the paint off the other car with WD40.

WD40 gets a bad rep as an all purpose oil, but it is a fantastic cleaner. I can imagine that it can also actually condition the paint. We normally don't think of car paint (clear-coat) as drying or porous, but it is. Meguiars M07, a paint conditioning glaze, is all oil. Some of which is petroleum based oil same as in WD40.

By the way, obviously wipe off the excess WD40 after you are done.

thanks for the WD40 tip.
My rear bumper (plastic) has paint marks left from someone that went to close.
And I have a small min-can of WD40 in the utility compartment
