I have a small area of surface rust above my wheel well. What's the best way to protect adjacent areas when applying POR-15?

When I used POR-15 for the same type thing I used masking tape to protect the adjacent area, but you should still be very careful because it tends to run under the tape. You can also wipe it off with a rag right after applying if you do it right away. The key is to realize that it has run, so you would have to remove the tape right after applying to see if you had any runs. If you did have runs, it will wipe right off. Use lacquer thinner to clean your brushes etc..., and if you need it to wipe off runs it works well. I was very pleased with the result of using POR-15, it was the first time I've ever done anything like that and I was pleased with the result.

I'm assuming you will apply the POR15 with a brush. The etching will definitely affect the adjacent exterior paint. You will want to build a ledge along the bottom of the corroded area using masking tape and cardboard to catch the metal prep. Take care to keep the corroded area wet, but not so much it flows onto the exterior paint. Once the area is etched with the metal prep the water will neutralize the acid of the metal prep. Dry thr area thoroughly and brush on the POR 15. Randy in Wichita

Any starter kit will work. Best results are when you can actually sand, or wire brush any loose rust first. The cleaner the surface, the better the POR-15 will adhere!

I agree with the previous responder. I would be careful using something that aggressive on the finish. Have had great results with Bar Keepers helper when nothing else worked...particularly around rust.

You don't need to buy any other items. I used BBs and EvapoRust Remover to remove the scaling and surface rust. I think the use of rust remover was over kill. Temp is critical and apply two coats, just to make sure everything is covered.

This stuff works great on our Cobalt hull. Our boat spends a few days in a fresh water lake and gets really scummy yellow. Just put it in a spray bottle (wear a mask and gloves) spray it on the hull in small increments scrub lightly with a sponge (mine is attached to a long handle) then hose off. It's like magic!

I'm sure it would depend on how bad the surface was. Mine was light / new rust. I didn't do any prep and had great results.

Id try something else like Semi-Chrome or Noxon. This is more of a Polish than a rust remover / Chrome Cleaner. Although it may do the trick, you can try it but Id say to buy a can, only if you have other uses for it... this stuff lasts a good bit and works great for shining stuff up.

I have and it worked great. Patched a spot on aluminum boat over the rustoleum and apllied paint again to top coat it. No problems at all

I suppose any good degreaser will do, but the tank needs to surgically clean. No oils at all. You need the metal prep. The metal prep roughens the parent material at the microscopic level, providing "tooth" or something for the POR 15 to attach to. There are other chemical preps that will do the same job, but you should use their material. Mostly because if you knew which materials would work, you would not be posting this question. Metal Prep is very good stuff and you can be assured it will do this very important job.A previous user mentions muratic acid. It is not a good substitute. It is more dangerous to use and does not leave a rust resistant surface, leading to possible rust formation as the tank dries.

I sprayed the wheel wells on my Ford Sport Trac and got very nice results. I did take the wheels off and masked the body near the wheel wells. This stuff will make mess due to overspray if you don't take the time to do it right. You will spend a lot more time cleaning up the overspray than you will taking the wheels off. Good luck!!

Here is their contact info. I would ask them directly. (I have rust spots bleeding through my paint from last year, but chalked that up to not getting it all off, and having spray shooting up underneath from puddles.) http://bondo.com/contact-us

I wouldn't use it to cover that, since rust will spread. It's to cover parts so they don't get heated up.

Definitely. But be sure to follow the directions when using the marine-grade degreasing kit before applying POR-15. Use a good set of gloves; for if you get some on your skin, nothing will get it off but time... a loooong time. Sand and then fine sand the surface before starting the project. Place some kitchen Glad-wrap over any unused POR-15 and press the lid on tightly. Store it in your refrigerator for future use. This is not an ordinary product. My air handler rusted out 5 years ago, and I saved it with this amazing stuff. I can't speak too highly about it.

I just use some today, and you do have to rub it sometime to get the rust to come off. I have seen the metal turn black and some time metal gray when the rust was removed. I love this product, it just saved me some tools that had gotten wet and rusted badly. I thought I was going to have to throw them away but it saved them. Well worth what I spent when I saved my Harley Davidson gas tank that rusted inside when it sat to long.

I have used this product on various projects. To get the best results, you should remove any excess material (loose and flaking rust, peeling paint, etc.). You can just apply it to any rusty spot and help interrupt the rust cycle. If you have too much material over the base/core rusty metal, it may not react to halt the on going rusting action.

this stores up ended with any problems. put some wd40 on chrome wheels to prevent rusting This is a great product.

I used the Rust-Oleum Industrial Choice Anti-Slip aerosol on a plywood wheel chair ramp. It worked great! I still have a partiial can and the only information about surfaces is: Indoor/Outdoor concrete, metal, ceramic, and wood. Might want to check their website.
