Rust under paint

What brand of paint do you recommend? Duplicolor?

 

I've only used HVLP guns to paint, no clue on rattlecan quality.

 

Luckily its on the roof

 

yep that's fine, its as good a quality paint as there is in rattle cans

 

Even if you wait till summer it's not going to be the end of the world. Just wait and DIY. You got it op

 

Thanks boss!

Thanks everyone for the replies, I'm probably going to do it soon, weather around these parts is bipolar lately I'm bound to get a warm day soon

 

Sounds like you have a handle on what is going on there. I would absolutely recommend doing it soon as you can. That may be in a couple of months, I get that, but don't put it off for a year. Too bad you weren't closer. We could have that fixed up quick for you.

 

In your experience, how far would the rust travel under the paint, radiating outward from the initial scratch? I figured it would be at max a 1/2"? I could be wrong though

 

No more than an inch, in any direction of the scratch. Your pic doesn't show any bubbling of the paint around the scratch so you don't have a huge mess at this time. Surface rust isn't a problem unless neglected and the oxidation begins to eat the material.

 

Sweet! Thanks man

 

You can flake that loose paint off and it'll break where the good adhesion remains. I doubt its an inch wide. Then you'll know exactly the scope of issue and the water won't have a place to hide anymore.

 

I would agree with what they said. I would at least flake off the loose stuff and spray some etching primer on whatever is there after you clean the rust off to keep it from getting worse. You will have to sand all that away anyways before you go to paint.

 

Yeah that makes sense. A friend of mine was telling me about rust inhibitor or dissolver and then the use of touchup paint as an option. Opinions?

 

this video shows you what a repair with rattle cans looks like https://www.youtube.com/watch?v=oyPsis_-fa4

I skipped the first video of him sanding it to bare metal and the bondo repair because I think all you need to do is repaint yours

 

I wouldn't bother. Rust you have is minimal and doesn't look like it's done any pitting. Sand it, prime it, paint it.

 

Rustmort and that kind of stuff for what you have going on would be like taking your money and lighting it on fire. Surface rust is surface rust, you can remove it with a scotchbrite pad from your kitchen. If you had serious pitting then sure, but really that makes no sense to me at least.

You have a basic repair right now, so while you can't take simple and make it more simple, you can definitely complicate the shit out of it.

 

See that suggestion was from my friends who drive Jettas that rust way worse than our tacos...

 

You're good to.go with sanding. Super minor rust issue in that scratch.

 

Yea just sand it out. Those rust inhibitors are for deeply pitted areas that can't be easily sanded or blasted.

 

I've had pretty good luck with rusting rock chips by just scraping the rust of with a pocket knife rubbing it down with rubbing alcohol and putting some touch up paint on it. I've never done anything that big though.
