Review: had to order from the US as can't find in the UK at the moment! - This is like Plasticine, and can fill really really big gaps as well as little ones. Very easy to use; doesn't need any tools, or even any precision as you can simply squish it into corners and awkward cracks. And you can take it off if you need to. No idea why I couldn't find a UK stockist - it's a very useful product - but the delivery from the US was just fine, and it actually arrived a week earlier than I expected. Recommended.
Review: So pliable and easy to work with, brilliant draught stopper - This caulking cord has been brilliant at stopping droughts from my windows, so easy to work with because it’s so pliable and easy to stuff into crevices. Doesn’t look messy at all if you do a neat job with it. Adheres to paintwork really well when well pressed in and stays put. An excellent purchase *****

## Questions & Answers

**Q: Can you paint over this product?**
A: I don't know for sure, but I have never tried to paint this caulk.  I would not think it would provide a good surface to paint, and flexing of the caulk would be a problem perhaps leading to wrinkling of the paint.  Also, the surface is slightly "furry" whereas I normally try to achieve a clean, dry and smooth surface before painting.
