| Post subject: | Rust Repairs - Leyland Roof Drain |
I have just started to do some rust repairs and have found that the roof drain holes don't actually sit low enough to drain the water away. Here is a photo of where the water is pooling. Same on both sides. I have repaired the rust holes but was thinking of drilling a hole in the area where the water sits. Just wanted to know if this is this a common problem and what have you done to fix it? Thanks Brad

I recently noticed that mine is the same. You could drill an extra hole there but at the end of the day, if the paint and primer is well and truly protecting the metal in that area, there is nothing to worry about IMO. |

I wouldn't trust my rust repairs - I am a mechanic  I will just watch it and see if it starts to go again. |

Drill there and you'll probably get a leak in through the door or quarter glass.

Mini turrets were attached with a continuous resistance roll weld (= a bigass spot welder in continuous mode with knurled, driven copper rollers). It leaves a knurled contact pattern in the bottom of the gutter, usually visible if you remove all the filler & paint. Drill through this pattern at your peril, as TK says you might get a built in shower. One other thing- The inside edge of the gutter was filled with ripstop putty? or something originally. It covered the lap joint inside. Many repaint jobs don't fill this or paint it properly. Then, it rusts. Maybe Sikaflex would do the job these days, but I found it messy to apply. (I'm a fitter, not a painter).

Hint on Sikaflex, (I work with it daily), I'd tape the roof turret up to the edge you want the sealant to go too (2mm or so up from the gutter fold), then apply the sika, wipe excess away with a gloved finger an inch or so at a time and wipe your finger clean each time, use metho on your finger (with a glove) to wipe it back and smooth it off, then peel the tape away and do a final wipe with your finger, metho and rag to smooth the tape edge down. |

Soapy water + finger also does the trick from what I've experienced |

Hey Kevin, some mini gutters appear to be spot welded. I did some repairs on a 67 deluxe recently and that was what I discovered. |

Roller resistance welding vs spot welding is a strange one in the mini world. No one is wrong or right, UK or Aussie they all flipped between the two methods at whil. Some outer sills are rollered, others spotted. |
