RIGHT LISTEN SO WHAT I SPELT SUMMIT WRONG WELL DONE FOR POINTING IT OUT.
1 thing i do say for brun if some 1 tell him summit, and maybee he thinks that aint right, he will go and look at places to see if it is true or not, then if he finds out it is wrong he will proove it.
as for you, you are wrong about t shirts not scratching your car, u may not be able to see it, but you are scratching your car by using a t shirt, as when u whipe it over the dust or small particles of dirt, the dust/dirt gets pushed in to the shirt as there is no where else for it to go. a microfiber however has large fibers, looks a bit like velcro, that the dirt/ dust gets trapped inbetween the fibers pulling it away from the paint.
it has been prooven that long term use of a t shirt or ne other CLOTH will put microscopic scrathces on your car, and after time will show up.
you may not be able to see them now but you will in time.
even if you go to a body shop and get some paint work done they will never use an old rag or old t shirt to polish.
you might think u know every thing but you dont, why dont you accept brun and others know more about car paint work or ne thing else than you do.
