    Small paint repairs, asking for advice!

    Afternoon all,

    Firstly, thanks for everyones generous input to this forum. I've been trawling all day and making notes in a workbook to refer to later on. (Normally it goes in one ear and out the other!)

    I've got some small repair spots on my defender to tend to (door rust, flaking paint), which will include body fill and repainting, which I plan on doing myself.

    However, I also have some other spots where i'm not sure of the best plan of attack because of their location.

    The rust doesn't look too bad in the photos below, just surface, but being so small i didn't want to have to create more work for myself then I need to by sanding back around it and spraying the whole section.

    Can I simply sand, clean, penetrol and paint with a fine brush? Or am I kidding myself?

    Also, theres a few little chips you can see in the first picture above the rusted section, how would i go about tackling these (as i have other places too)?

    Many thanks!

    Thomas

    and because we all love photos! (plans to fix up a few niggling spots, remove snorkel, maybe new roof racks)

    I did find this in another thread, specifically relating to seams. Thoughts?
    I'm not saying its wrong, just if its suitable or not for my application.

    Cheers!

    • let the Penetrol cure for a few days then brush an epoxy enamel over the seam
    • Sika 227 seam sealer wiped over the seam with a finger
    • Painted the 227 in topcoat to match firewall


    All the seams still look good 4 years later.
    A simpler option might be to wirebrush, Penetrol than apply a coat of lanolin spray.
    Whatever you do, I suggest Penetrol should be part of the solution.
    Checking and rustproofing Defender firewall and door frames (remove door trims and spray inside box sections) every few years is good insurance.

    Just had an experience where I wanted to repaint a small scratch on the roof of our Mazda, but the particular shade of blue is not generally available.
    I'm still trying to get it through Mazda, but meanwhile was advised to do the following:

    1. Use an earbud to apply rust converter and let the vehicle sit under cover for several days while the converter works.
    2. Buy a bottle of clear nail varnish and apply a coat over the scratch, to seal it.

    So, that might help, maybe.

    Rust Buster is fabulous and works a treat (buy from Bunnings) dab it on those rust spots with a paint brush. Then after it's done its thing you can sand those areas and apply paint. The chips can be touched up quite well even with the touch up pens these days (they are not too bad) You just need your paint code I am a qualified spray painter (retired through disability) so you are more than welcome to pick my brain for all info and any help I can offer

    I second the rust buster, I have been using it for a decade or more, even on an ex mine vehicle.

    Just make sure that you don't let it run down the panel as it will damage the rest of the paint.

    For your job I suggest getting a cheap 25mm brush and cutting the bristles in half so they are shorter and stiffer, tip some rust buster in a small container, dip the brush in and wipe off the excess on the edge of the container. I cut the bottom of a 600ml coke bottle and use that as a container. Leave it for 24 hours to do its job, wipe off excess with damp rag, dry then paint. Simples

    Guys, thanks so much for the fast responses, I really appreciate the input.

    So it looks like a bit of carefully applied rustbuster to those areas is the go.

    Now, please forgive my lack of knowledge in the area, but Epic_dragon, im looking at you - whats my best plan of attack after this step?

    Does it still need to be sanded, and if so, how much?

    Or is it a case of just painting as is (after rust buster has been removed and wax and grease remover applied aswell)?

    And, for such a small area, brush?

    I'm only asking because I have to replace a few rivets, and i'm going to have the same issue with painting such tiny areas!

    And thanks DiscoMick and Corgie carrier for the help too - noted, and appreciated!

    I think given how small the area is, I would definitely not sand and would brush touch with the touch up pen. The rust buster will do a lot of the work

    Hi E.D.,

    I'd like to take you up on your offer of advice, as lately I've noticed a chalky patch of paint above the driver's door , at 1st I thought it was soap residue from the car wash, but I have a horrible suspicion the clear coat is about to go and was wondering if there is anything to prevent this, to even "feed" the paint. I've had success in the past with Motospray AutoRestore IIRC, for a patch of plastic on the rear bumper of my D2 that faded to grey, after I put a hot kettle on it, mistaking the raised footstep pattern for checker plate. After a few applications it returned to black and eventually couldn't be seen. TIA.

    P.S. The vinyl/plastic restoration product was actually called RestoreAll and was made by Hichem in Hallam Vic but Rustoleum bought them out https://www.architectureanddesign.com.au/suppliers/rust-oleum-australia/rust-oleum-corporation-buys-hichem-paint-technolog#.
