Has anyone drilled better drain holes under the sills. Mine regularly block so I'm thinking of drilling more near the back.
If so, what diameter? David.
 
I'm a dab hand with the angle grinder :lol:lol:lol

I'm assuming you've tried unblocking your old holes, normally they seem to be good enough. Surely danger with drilling the sills is there is little enough good metal to begin with.
 
When is a hole in a sill a hole, and when is a hole in a sill an MOT fail?:nenau:nenau
 
I have drilled a sill before now, to cover a rust hole. I put a grommet in hole and said it was a wax oil point.....result!

Ah, having 25 waxoyl grommets on the sill might be a giveaway though...:lol:lol:lol

Tear along the dotted line...:lol:lol
 
Seems the old tin worm is a common problem. Maybe I'll just make the original back one a bit larger. David.

Interesting question!!!! I appear to have a few water blisters on mine, I might drill a hole in each one, pop the blisters and smother them in Waxoyl again, I'm waiting for the right weather

I wont make the mistake of doing it on my own drive again and I for sure wont be getting washed off by two women like Alex :lol
 
Sills rot from the inside. If you can see bubbles your sill's goosed :eek:
 
Depending on how bad it is you can patch it, you won't know how bad it is until you start cutting the rot out.
 
There's another thread running on this subject at the moment. My thoughts are a long term fix is to fabricate new sections, preferably folded to shape the outer sill. Easy fix is patch and patch again a year or two after.

Linky? I'll be keeping a close eye
 
I would but I haven't learnt how to do that with an iPad:doh

I'll be on the laptop later so I'll do it then.

if its just a small patch you need, and you do the cleaning up and painting afterwards give me a shout. full sill is too much prep for me at my time of life
:lol:lol:lol

not all "water blisters" are from the inside. stone chips etc can cause paint imperfections,add to that frost etc. best thing is to burst them and apply a neutraliser or totally rub back and repaint. catch it quick if you can. during my years in the "wilderness" i also did a 3 year body repair and painting c+g course.
