Unless you really want to stink the house out! Hammerite seem to have formulated the paint for 8-25C ambient according to the web site.

Pretty sure it crosslinks as it cures so the final Hammerite paint finish after full cure is fairly resistant to solvents. The new stuff now has been meddled with and isn't as aggressively xylene based. -- Regards, Martin Brown |

Yes - I did this many decades ago when I needed a rock hard finish fast on a few brackets. 100C (or a bit hotter) in an oven for 2-3 hours did the job. But it will stink the kitchen out, so wait for SWMBO to go shopping. Pop yer gearbox in the dishwasher at the same time ;- Best to let the piece cool in the oven too - the paint can be a little soft at that temperature even after baking - but will be rock hard on cooling. -- Tim Watts |

ICI bought out Finnigans Speciality Paints, and 're-formulated' (cheapened) Hammerite to be white spirit based, rather than the Xylene that it used to be based on. Result is it never gets as hard as it did! Xylene based hammer finished paints are available from other sources. AWEM |

AWEM Thanks Andrew With the newer white spirit-base Hammerite is there any benefit to be had by baking it? |
