Why not go the whole hog and use Pritt stick?
Now I've tacked welded my new sills on I've decided I'm going to save time and fully rivet them rather than weld them. Bernie said it'll be ok so thats good enough for me, him being an expert and all thatSo do I go with aluminium or stainless rivets? Decisions, decisions....
Or save the cost of new sills and do a common 'in period' bodge repair of the 1960/70's, just cover the rust holes with some fibreglass matting + resin, skim over with filler and finally finish off with a good thick coat of black bitumastic underseal.
