## Questions & Answers

**Q: Can you paint this caulk with regular primer+paint in one paint?**
A: Yes. Just don't paint too soon.  Check directions.

**Q: Does this product attract dirt? Is it easy to clean?**
A: It is non hardening so dirt can be attached to it over time. 
We clean the exterior with water and the interior areas with a paint brush and shop vac. It is very dusty where we are tho.

**Q: Can I put this on something that’s wet or damp?**
A: you can but its best if its clean and dry

**Q: Good for exterior aluminum trim for widow against brick? Or aluminum trim againsts wood?**
A: The general rule is to use a silicone or tripolimer on aluminum. I personally would use Geocel 2300 for your application.
