Rust

[redsarrow]

What is the best way to get rid of Rust?  My DH has been sanding away at the trunk lid and it just doesn't seem to come off (using 80 grit sand paper and a hell of a lot of foul language)

Would a Rust Inhibitor do the trick?  How do you guys do it?  There has to be an easier way than sanding the whole thing!!

DH mentioned an Acid Dip... but we were not sure if you can do this without removing all the old paint?  Anyone know?

And my last dumb question for the day... is anyone in or near the Maryland/DC/Virginia area and know where we might go to get some help with this big green monster?

Looks like you have a job cut out for you.

I'm not a pro or anything, but I'd thought I would throw in my 2 cents.  If it is just surface rust, then I'd recommend some of these:  http://www.levineautoparts.com/3mgrco2rodi2.html

Of course, you'd probably want bigger ones that would go on a grinder, but I used some of those and hooked them to my drill.  It grinded to surface rust that I had to bare metal, so it works pretty good in my opinion.  Your local paint shop should have some of these.  You might also want to ask how big do they go since I'm not sure on that.

If it's a really bad rust spot, then you may have to cut around it and replace it with new sheetmetal. 

Before you go out and get some discs - you may want a second opinion.  Like I said, I'm no pro, but I'm learning each day

Good luck with your project!

I used a 'paint and rust' removal wheel that was made for a drill
not only did it remove paint quicker but also cleaned rust out of pits
once it's epoxy primed, it shouldn't come back!

should be at any automotive store

i media blasted all the body parts. comes back all fresh metal but if it's real thin, it could make a hole . Rene

If you have it dipped it will take all the paint off. The old way of doing it was sand blasting. I don't care how fine the sand or what angle or the pressure. Sand blasting will warp the metal. If you block the car correctly you will find this out. If you don't block the car you will see it when you paint the car. You can have it blasted with garnet. I have had good luck with that. If expense is of concern. Then the Strip and Clean disk (3M's name for it) is the way to go. After you have used the disk to remove as much of the rust as possable. Then you need to use a product that is called Metal Etch. This is an acid that dilutes with water. This will kill any rust that is left and clean the metal for priming. When the rust is black the etch has done its job. If after using it and it still has a rust colored look to it. Then you need to go back and hit it with the wheel again. Like was mentioned before. If its too bad it will need to be cut out and replaced.

Hey Drop Top

Do you wish you had a dollar for every time we said that?

[Drop Top]

Sometimes I feel like a broken record. Don't you? 

[69hemi]

Yep!

Can POR15 be used on the exterior of the car where it will be painted? 

[Drop Top]

Yes but make sure you fallow the directions. They call for a tye coat of sandable primer to be applied before the POR sets up completely. I don't use their tye coat. I prefer to use the blocking primer that I always use. As long as it goes on before it gets too dry it works fine. If you Waite too long, you will need to sand the POR before you applie the next stage of primer.
