## Questions & Answers

**Q: Is the cap area large enough to refil the cans? I have a 5L can of dinitrol and so if cans were tefillable i could just pour into the cans.**
A: Yes - these cans are for the Schultz system I believe it’s called and you connect them to an air hose. The top unscrews and you can see see straight inside , no baffles. A bit larger than the top of a plastic milk bottle. It’s rather thick stuff so difficult to pour but possible if you warm it first

**Q: does this come with flexible wand for the spray nozzle**
A: No it does not as the product will not go through the wand

**Q: Does this need a air pump?  If so, can a electric tyre pump be used?**
A: You will need a portable air compressor designed to be used with air tools, a tyre pump will not work. This product is available in aerosol form as well. It's a great product I've used it to protect the chassis of a land rover defender. Can be messy to use though, keep it off your skin, difficult to remove.

**Q: Can this be brushed on?**
A: Yes can be brushed on stand the tin in hot water first
