When we speak of sealing, I think the consensis is, either Klasse SG, BF II, Platinum, or another type of polymer/acrylic/synthetic....Klasse is a little more forgiving on white than any other color, same with Blackfire and Platinum....As for Carnaubas, they really dont hide or fill swirls, give it a wash or two and there pretty much gone for filling purposes, or the temp's will just plain melt it off.....Some prefer to use them on a regular basis (monthly, or every wash even) You need to take care of your swirls and filling prior to sealing...And you do that with glazes....As for polishes, and if your paints in typical condition for its age, stay with high quality stuff, the Klasse twins (as reffered to), is a great choice....There are many options to use, your best bet, is to single out, what you dont necessarily care to work with, because it doesnt work for you. In other words, experiment, whats good for me, may not be for others....You will find many users on here using Klasse, Clearkote, Blackfire, Platinum, P21s, S100....Souverign(sp) (Pricey), Poorboys....the list could continue for at least two more lines !!! If its basics you have to work with, go with the Mothers 1-2-3 punch !!
