Mirko all fine and dandy in an open tube dob which probably benefits from being hosed out occasionally to get the dust out.
But closed - tube SCTs, Maks and refractors are another matter entirely where there is a considerable degree of precision involved in their assembly and they are not intended to be opened by the owner and doing so raises considerable risks of damage to the optics.
Secondly as Alex points out no manufacturer has ever flocked their OTA - not even Questar, TEC or AP - for good reason.
