Removing old firebox paint from an SE1firebox paint is scorched...going to repaint with black glossy VHT Caliper paint.Paint stripper gel or caustic bath to get the old stuff off ??

Personally I'd stay away from the caustic if you are unfamiliar with it.
The gel works well but may take a more then one application. I use the electrical method which removes all paint and rust leaving you with little more then a brush up and a rinse to do. http://modelsteam.myfreeforum.org...3.html&highlight=rust+removal |

Depending on the paint, you may be able to get away with soaking it in acetone. Leave it for a while, then go at it with a wire brush and the paint should disintegrate pretty quickly. It has the added bonus that it's basically just alcohol, so it's safe to touch and just evaporates off the piece when you're done. I don't have any other experience with either of the other two. | ||||||

Another method to remove paint that many members use is to take the firebox in this case and immerse it in a pot of boiling water with dishwashing liquid added (I think it's called "Fairy Liquid" in the UK) ....boil until the paint simply falls off.
You might have to help it along with an abrasive dish scrubber pad and an old toothbrush, but it is a relatively mild way to remove paint without the smell and general nastiness of using chemical paint strippers. |

I use Nitromors. It's nasty stuff (use plastic gloves) but very effective. The scorched paint may be reluctant to come off with any method. You may have to resort to emery cloth or wet-and-dry. Personally, if Nitromorse won't shift it then it's stable enough to paint over! | ||||||

ok. thats one i hadnt heard of before.... interesting...any idea how long the process is ? roughly of course... |
||||||

I did it once and it took about an hour simmering on the stove at relatively low heat...just enough to cause a rolling boil. I used a large pot meant for cooking lobsters, so it took 30 minutes for the water to reach a boil..THEN I put the firebox in and let it boil for about an hour. All the paint almost fell off with gentle nudging by a toothbrush and scrubby pad and a pointed pencil with lead broken off for the grooves and tiny spots that are hard to reach. It is a longer process than chemical stripping, but if you don't burn yourself it is not harsh on hands, lungs and eyes like the chemical stuff is...AND the chemical stuff is expensive, water and fairy liquid not so! |

Boil till the firebox is "al dente" 
Reminds me of the classic method of making goat stew. |

| Roly Williams |
What's that? "First drown your goat then light a fire under it and leave it over night"? |

sounds like Pukeko stew put Pukeko in pot with water and stones boil untill stones are soft then throw the Pukeko away |

the electrolysis method works and I also use
Caustic soda and warm water (gloves and eye wear recommended) far quicker than boiling in laundry powder |

I put it in my blast cabinet which has glass beads in it.

I use Nitromors paint and varnish remover and it works great for me but it is quite harsh for the skin so make sure to wear gloves and protective eye wear if you decide to use it. |
