Just to balance this a little more evenly perhaps and based on experience when I removed my CP?

Yes gaskets are necessary!

Decent CP kit will come with all the fixings which are usually countersunk cross head bolts, nuts and washers. It will also come with the necessary gaskets if sourced from a decent supplier. It is I who has used butyl pondliner on numerous fittings to include door hinges, hinge blocks, swingaway wheel carrier, bumperetttes and probably lots of other things I cannot currently recall. Gasket is better than none in my book as it assists in filling any voids and prevents the migration of dirt, grit and moisture between mating surfaces. I also have a tendancy of 'wet assembling' all the fixings with a decent marine grade sealant and wiping off any excess after fitment.

As for sills I would strongly advise the fitting of gaskets, I used a wallpaper scraper to get the crud adhered to the sill underneath off when removing. Mine obviously didn't have gaskets at the time. Sourcing and making gaskets costs very little time or money and I can see no justification for not fitting them. See my post bottom of page 1.
