dear abdullah bhai
meguiars #16 wax is from professional line , it was initialy launched for europian market however now its obsilate verson and meguiars #26 wax take it place , kashif bhai and usman bhai are satisfied user of this wax
poorboy's one of my favourit brand due to its quality products in most compititive prices 
poorboy's having 2 sealants and have tested both 
1) ex sealant with carnuaba
its hybrid sealant means mixture of synthetic and natural carnuaba , its all alone one product and no need to topup with any other things as natural oils in this sealant give depth to paint and synthetic elliments seal the surface for longer time.
i personaly like it on dark paints however u can also use it on any colour, its easy on easy off, even can apply under direct sun
well being natural oils in it its life is not longer, so last just 2 months in extreem weather like we living
since i regulaerly maintain my cars so i am good with this life.
I LIKE IT
2) ex-p sealant
its pure synthetic sealant
same like ex sealant with carnuaba its easy on easy off, can apply under direct sun, life longer than ex sealant however shorter than klasse sealant , streangth wise poorboy's both sealants are not good but if applied on proper prepare surface than u can easily last 3 months with this sealant, i would prefer klasse over this sealant intearms of longer life and out comes of both sealants (ex and klasse are same just klasse last much longer than this )
so when u coming lahore to test these sealants ?
