Had a bad day yesterday and managed to chip a new Caroma Stirling porcelain enamel steel bath I am preparing for installation in a bathroom.
It's only a small chip but will get wet everyday as it's right under the overhead shower.
The chip measures about 4mm long x 2mm high in the centre where it's back to the metal (black area in centre). The wider area of damage to the white orcelain enamel is about 9mm long.
I've read a couple of posts here and elsewhere about some of the repair options available.
Selleys Appliance Touch Up - about $17
Tubby DIY Chip Repair Kit - $55
Selleys Porcelain Repair - $22
Caroma Enamel Repair Kit" - - $70
My major concern with any of these repair solutions is that the paint/filler will absorb a tiny bit of mositure and the metal underneath will begin to rust. I have visions of it looking fine for about 5 years and then ever increasing brown streaks to start appearing as the metal underneath rusts. I will be living in the house for another twenty years so am looking for a good solid solution.
In the past 15 years, I've tried many "rust proof" paint solutions on outdoor projects, car floors etc. White Knight Expoxy enamel (with its related primers) has been pretty good on some of these projects but eventually breaks down after about 10 years - sooner if there had been any rust underneath, even if brushed back to "bare metal". I called the White Knight Support desk yesterday and they said the Expoxy enamel would yellow over time. He even suggested a product from a competitor - the Selleys Porcelain Repair Kit.
So I'm wondering if any one has had long term success with any chip repair solution on a porcelain enamel steel bath? I'd be particulrly interested in any feedback on the Caroma Enamel Repair Kit as I can't find any comments on this at all. I suspect it's just a paint like the Selleys Appliance Touch Up, but marked up $$$ as it carries the Caroma name.
Any comments much appreciated, Davo
