Finishing sealant to reduce tackiness
I'm quitting after the first two pages of few searches of the web on this, and turning to folks who may have solved this.
I'd like to finish ridge-line silicone seam sealer after complete curing, one day, a completely tack-free surface before it coheres to itself and before dirt adheres to it. If this were a tire tube, I'd dust it with talc.
Has someone come across a product or method to do this? Maybe some kind of non-toxic but transparent dust? If this were a tire tube, I'd dust it with talc.
The sealant I've used is the much-liked Permatex silicone windshield sealant, which has excellent wetting and adhesion properties.
