I just recently bought my car and they put some type of sealent on it because i saw how smooth the showroom cars were and told them to do that for me on mine and they did, for free...

Question is its getting DUSTY, should i wash it or what. How do i clean it off? Also, When i want to wash it do i have to take the sealant off or something or just wash it with car soap??

 

A sealant is used in the same way a wax is - treat it as such. Wash normally, the sealant will naturally deteriorate in a few months (you'll notice water not beading) and you'll want to get your own bottle of wax or sealant to apply when it does.
