Sealant to increase Water-Resistance of SLS print We are attempting to print some single-use prototypes using an SLS printer. The parts must be somewhat water-resistant for short-term usage, but do not have to been waterproof entirely. 

According to this page, Post processing for SLS printed parts - Water tightness, any silicone type or vinyl-acrylate sealant should work well, but I was hoping that the Stack users here might have some specific suggestions. 

Does anybody have specific recommendations for sealing SLS prints?
SLS prints from nylon are somewhat porous. This means, that they will let a stabilizer soak into the outer surface to some degree.

What kind of stabilizer is needed is depending somewhat on the properties you want, but generally I believe these might be useable depending on the viscosity:


2-component resins could be used, but they are usually very viscous. Their viscosity, however, is dependent on the exact type and mixture and could be altered by temperature.
1-component (air-hardening) resins or resin lacquers can be thinned to achieve a solution into which the item is then dunked and dripped off. How much thinner is adviseable depends on the exact material
Nitrocellulose lacquer, like it is used in guitar building, is extremely fluid and could be used for treatment via dunking.
PU lacquer could be used too.
