Happy to help. Yes, Bondo can be used after applying Rust-Oleum Automotive Rust Reformer. - Rust-Oleum Product Support 6
Glad you asked. Rust-Oleum Automotive Rust Reformer can certainly be wet and/or dry sanded. Keep in mind that a topcoat can be applied after allowing 24 hours of dry time. - Rust-Oleum Product Support 5
I have used this product on rusty surfaces and it works remarkably well, however I have not used it on things that are regularly exposed to water/moisture. I do believe that it is worth a try. Thanks
If its fresh paint it can come off with GOO gone
Yes but I would wire wheel off any paint in the area to be welded so as not to contaminate the actual weld as part of regular surface prep for welding.
This will work fine on black pipe but you will still need to clean and prepare the surface thoroughly to get the best results. That being said when it comes to preventing rust, just about anything you coat the metal with is better then nothing on it. This product works very well on bare metal but I would still advise either a metal etching compound or a self etching primer then a coat of this. Painting is like welding as where the saying “Cleanliness is Godliness “ applies. The more work you put into the preparation the better the end results will be and improve the longevity of all your hard work.
I assume you have shaken each can vigorously until the rattle ball inside is free and doing its job (I have a small air powered paint shaker for this) The tips may be clogged. If so you can carefully, wearing eye protection, remove the presumably bad tip and replace it with a similar tip from another can that you know works. It is easy to inadvertently spray paint all over the place while trying to do this, so be cautious. If changing tips doesn't help, the last resort is 10 - 15 minutes of vigorous shaking to see if you can loosen up enough sediment in the spray tube to get the paint to start flowing (spraying). If that doesn't help it is time to toss the cans, either by depressurizing them and emptying out the paint to use as a brush-able product, or take to a facility that will recycle them appropriately. NEVER just toss them in the trash.
Thank you for your answer. The pipe and fittings alone would be about $700 online and a couple of hundred more to install. I just need to at least slow down the pin-hole leaks for a few months until my family has moved out. The pin holes are scattered and very small, but the integrity of the pipe is still pretty solid. I am surprised that there might not be a paint, or product, that could simple temporarily plug up these pin holes. I did try FlexSeal spray but it did not work. ( I think I may not have allowed it to dry enough before flushing toilet) I am considering FlexSeal tape. Might that work? Sorry to be a little off topic! Anyone else with a suggestion would be very much appreciated. Thanks!
Just about anything is better then nothing when it comes to preventing rust on metal. If you clean and prep the material in advance this will certainly help prevent the rust. A lot of products are manufactured using powder coatings and in order for this to help it would need to be cleaned and prepared in accordance to the label and I would advise putting a top coat of enamel over this to thoroughly protect your project and you could match the existing coating closer
Depending on how thick a coat you apply, it could spread only 10 feet, but then again more sparingly it could cover 12 Square feet.
