Fender rust disguise

good plan, wire wheel the rust sports, por15, and cover it all up with a big ass bandaid! $20 sounds like a great deal. Remember anywhere POR15 is used , it must be top coated while still a little tacky. It will break down over time in the sun's UV rays.

they are still just vinyl stickers. Any bumps from the rust will show up. sand it down, POR-15 and cover with plasti-dip still removable, easily touched up, and flat black texture you could blend anywhere ...not limited to the pre-cut vinyl.

The problem is that on the early TJ fenders it isn't as easy as 'grinding it down'...most of the time they rust through from the bottom as there's panel underneath that allows water/mud/etc to get sandwiched in there. The only way to truly rid yourself of the problem is to cut out the affected section and replace or simply replace the fenders. I've got the same issue on the blue '97 I picked up and if we keep it I'll eventually pick up a new set of fenders, until then I'll ignore it.

POR 15 comes in small containers. Kuncles sells it. I bought a quart the last time. Why not just buy the Krylon anti skid in a spray can. Sure seems like the cheapest bet yet. My mom's TJ has had the who;e front fenders sprayed in it. Covers the rust up.
Who painted it? To get rid of rust it has to be sanded down and sealed. You had that painted pretty recently, I would take it back and have them fix it.

Like Ian said, it comes from underneath.

You will never sand it all out.

I just had to replace both my fenders on my yj... Because they didn't fix the rust properly and it bubbled up and well let's say I got tired of looking @ it and tore them off.... If I could figure out how to post pics I would. Know anyone who does paint jobs for cheap?

you used to be able to get it in pint containers. when my friend sold it he sold a lot of pints. The underside is the most important side to do since it will see the mud, salt, and whatever the most. Another product that works well and is easier to use than POR is Extends. I think Permatex bought it and sells it under another name. You strip the area to bare metal, coat it with this paint, wait a few minutes and paint again. Then let it sit overnight and it will turn black. Then you can top coat it.

If you have a 4" grinder you can get various types of wheels for it. They make flapper wheels with a course sand paper on it that will work well. I've had a lot of luck with these blue plastic abrasive wheels (I think they are called zip strip or something). They'll take the fender down to bare metal in seconds and leave a nice smooth finish.

Taking the fenders off will make it easier. It's only a few bolts. That way you can take just the fenders back to the guy to repaint them.

Ever seen the area I was referring to? If it's bubbling on the top side by the time you grind it out you're gonna be left with a hole, not 'bare metal'. Anything short of cutting out and welding new material or replacing the fender will just delay the inevitable.
