Knifeing putty.

With this hot dry weather I decided that it is a good time to look at my paintwork on my neglected Traveller. I wanted to fill in the small blemishes that the seagulls had made on the ally roof. The local motor factors no longer sell knifing putty so I made my own. I sprayed some red primer into the plastic lid and mixed in a quantity of talcum powder. This made a thick paste that filled the cavities and after rubbing down with wet and dry the paintwork became smooth and flat.

Also called “Stopper putty”, should be readily available.
Bet your smells nicer though.
Will be interesting to see what happens to the top coat.

When I put the bilge keel back on my boat there were gaps between the keel and the hull.
To fill the gaps I mixed talcum power and resin together and pushed the mixture in between the bilge and keel before tightening the keel bolts and scraping off the squeezed out excess - worked a treat. :D

Let us know if it takes paint well.

I have only used spray cans but it works fine. Talc is an inert powder so it shouldn't react with paint and yes it dose smell nice.
I wanted to fill the gap between the roof and the gutter on the Traveller so I mixed a small amount of fibre glass resin and talc with a tiny bit of hardener. This filled the gap fine.

Great, that is handy to know, never thought of alternative uses of Talc before.
