So she's stripped but the sills were not good so I have two new ones to go with her to the paint shop. BUT what was she like under those rotten sills? Well it could have been worse, the sills are toast as suspected but the inner sills only had surface rust which was quickly taken care of, then a good coat of metal stabiliser put on and left to dry over night.
Next several coats of Zinc primer and looking like new again. Next job is to Waxoyl
(NB other brands of wax protection products are available
) the inside of the inner sills with aerosol Waxoyl and when shes back from the sprayers I'll Waxoyl the outside of the inner sill, the inside of the outer sills and have the wings off and do behind those too.
Not to scare anyone but the rear of the sills were crammed tight with muck for about 6 inch's, if you've never had them off and your sills are still in fair condition you may want to consider a winter project.
