    just sprayed the Rear Level Sensor Brackets with 2 coats of Hammerite, to upgrade the poorish MB paint finish ( a few scratches here and there) guess these parts are just chucked in a logistics bin, until picked.

    Let them air dry in warm house. First coat overnight and this 2nd coat 3 hours.
    They are almost touch dry, but a bit 'almost' tacky.

    So as the wifes out, I thought I would pop them in the fan oven for an hour. Air plus heat hoping it would accellerate the drying process.
    Just so the paint is hard whilst fitting

    Will it ?

    But at what temperature?

    Initially put on at 40C lowest oven goes, seemed hardly luke warm, so increased to 80C
    Is that about right.

    Or should it be like 120C?

    Car paint is bake hardened in plant at 150-180C dependent on the specific paint formulation (and plant). Some can go over 200C.

    If your wife is anything like mine she'll smell that as soon as she steps through the door and then you'll cop it !

    When baking painted parts in the kitchen oven there is also the added bonus of having Hammerite flavored pizza for a few weeks , or how about a Hammerite infused cottage pie.

    When the wife eventually starts talking to you then she will inform you that you are an idiot , dont take it personally i didnt when i dishwashed a set of engine casings covered in Gunk which took a few deep cleans to rid the DW of the odour.

    I have found with Hammerite a couple of days on the radiator cures it well enough to be used and handled.

    Thanks, an hour at 80C and left in oven for half hour till it cooled and they seem dry :)
    Not sure if they are "cured / hardened"? Or as if air dried for longer.

    Just hope the paint is not weakened by it.

    So now put on cigar tins, on a double vented radiator, till required need some clips for the oanel under the lower suspension strut. Cant be arse to fight with mangled ones for £6.

    Thanks finished at 2.45 pm and left the hob extractor fan on .
    Doesnt seem to smell :)
    Maybe its the fan in the oven or the fact the first 3 hours when they really smell was outside the oven :)

    She hasnt noticed he he

    Blimey I wouldnt put anything in the dishwasher ... surely the grease and smell would get recycled into the salt reservoir!!!

    Hammerite is enamel based so it will take 7 10 days to cure
