I used to use Ragtopp and to be fair it gave beading for the longest time out of any of the products I have used. The problem is unless you apply it inside a garage or there is no wind at all, half of it blows away in the wind as it's an aerosol. Autoglym is much easier to apply. The other good one is the BMW stuff... not too expensive but you kind of have to brush it on.... works well though.
