Any one sprayed rattle can laquer on a deliberate made rusty frame

Have a steel frame that has had all the paint removed and left to go rusty. Looking to seal the rust in by a coat of laquer.

Anyone done this before and any tips to get the paint to stick.

Thanks

The process will continue underneath the paint. You therefore can’t achieve a permanent result in terms of durability of the paint job.

^ That.

Lacquer is water permeable and without any anti corrosive properties so will never stop the rust for long, with it already having a hold it’ll be even worse.

You can keep on top of it and keep knocking the rust back with some scotch pads or similar and re-lacquering but it’s not like you’re going to freeze things where they are right now.

If you’re never going to paint it then you could use Ankor wax. Apply a couple of coats let it dry, give it a buff and it’ll last for a year or so before you need to add a bit more.

You can find it in small quantities on evilbay

As you and @M_V say the rust will never stop but IMO as long as you get good adhesion will be fine for a few years and you have the texture and colour of the rust. Have seen architectural and art pieces that have been coated with an epoxy clear coat and that seems to seal the metalwork. It is an 2 part epoxy paint that is uesd on oil rigs so should be good to use on a frame. But can you get that stuff in a can or need compressors et al.

Wonder if using a harder plastic clear coat be sufficient or or would a plastidip clear coat be like a rubbery cover that can stretch so the surface stays covered as the rust expands.

Or if anyone used a clear epoxy paint. As that will seal the metal. Then gives me the idea can use a spray glue to seal the frame.

Will re edit later as the sedation is still not clear.

Ended up using halfords laquer cans that were old and had leaked.

Sprayed in bad lighting and there even are a few drips that haven't hardened yet after 5 days. Overall the worst rattle can job I have ever done.
