hey people any of you use these ceramic coatings ? "Hydro Silex"  I have just seen this  one, over the counter type,  advertised it comes in a trigger spray & available at Repco , $27 are they shit hot or just shit , I use a good quality spray wax polish  called FW1 & its really great lasts for weeks . my question is will this ceramic coating allow the wax polish to last longer & look spunky for a greater time &  would the  difference to an professionally applied be noticeable cheers
