    Does anyone know of a fuel especially meths resistant clear gloss lacquer.
    I have made a mistake and seek to recover the position.
    After carefully stripping a 22b tin I have coated it with stove paint suitable for log burners BBQs chimineas etc looks good!
    Wrong! it’s not meths resistant, damn!!:rage:

    Engine lacquer may be an answer?
    Cheers Nick

    I have some items painted with engine enamel(not lacquer) and can check meths resistance tomorrow.

    I use generic clear synthetic lacquer, after a good hardening time (a week or so), its meths resistant.
    It isn't solvent thinners resistant and you have to be careful with Naptha, but otherwise it stands up OK.

    Oops didn't see clear gloss!! Doh. I have found that VHT clear lacquer isn't much good for panel wipe either.. obviously does what it says on the tin.

    I would think that the curing time might be a necessary factor no matter what paint you choose. Weeks or months.

    No good, mate. The clear on the 8R is Rust-Oleum VHT clear, the orange on the fuel can is Dupli Color Chevrolet Orange. Meths from my Trangia fuel bottle was immediately damaging to both.

    I also have Dupli Color Ford Blue and Cat Yellow, but didn't expect them to care any better than the orange, so didn't try them.

    Edit: Ken's got a good point about curing time. The clear was cured for years, the orange for months.

    Duplicolor makes a ceramic engine clear in both gloss and matte. It seems to resist CF, DNA (meths) and the other liquids I usually have on my workbench. Paint stripper will remove it though. I use it as a finish coat on pretty much all my repaint jobs. Never had a problem usingit over Rustoleum, Duplicolr or Krylon color coats. I do, however, cure the color coats for 30-45 minutes in a 170-200F oven before applying the clear coat, then it also gets a trip through the oven.

    I use automotive paints, and automotive clear coats.

    I bake them at the recommended temperature, or if no recommended temperature, ~64°C for an hour or more.

    Note: Don’t use very high temperature paint (eg requiring curing at 200°C) on parts that are soldered.



    Cheers

    Thanks for all of the input gents.
    I have put the tin through two 1hour curing cycles at 240 degrees and it seems a bit less susceptible to the meths according to instructions it needs a third at much higher temp! So may just give it longer at the 240 as our over, won’t go higher then choose one of the above suggestion.
    @Marc thanks for checking out your paint jobs for me Much appreciated!
    @cottage hill bill I will check out the ceramic lacquer you have used.

    @Tony Press top tip on the curing with soldered parts!:thumbup:

    Cheers all.

    Glad to be of service, sir.

    Looks like the baking to cure is key, I didn't do that on either of my test subjects.

    Unless you are using it on a part that is going to get that hot, you don't need the third bake for VHT paints. I've painted founts, burner frames and suitcase cases with only the 30 min/200F cure with good results. If you're painting headers for your car, do it like they say otherwise you can skimp a bit on the cure and save some time/effort.
