Anyone ever tried spraying shock cords with fire retardant?
Yes. I buy the tubular kevlar kind. I spray that shock cord right into my rockets.

check out this shock cord that's been in use for years with no problems.Applying a fire retardant is applying a chemical concoction to a solid in the hopes of improving fire resistance. But, people here are looking at applying fire retardants to things that might not have been the originally intended material.
Shock cords are structural items. If you are going to apply a chemical to them, then you need to ascertain what this does to the structural properties. As a for-instance, apply oil to nylon. Wait a few years. Pull it apart with your bare hands.

+1, and the retardant solution only protects them from actually burning, not from the heat itself which is what damages nylon and elastic the most.complex solutions to a simple problem...begging for a failure.....
just use kevlar.
This is what I was wondering. Actual burning does not seem to be the problem, but I've certainly had elastic shock cords get charred and significantly damaged when the chute gets jammed. Untreated elastic seems to do just fine when the ejection works correctly. I *do* use Kevlar from motor mount to just before the end of the BT, so all my elastic is always on the safe side of the wadding.+1, and the retardant solution only protects them from actually burning, not from the heat itself which is what damages nylon and elastic the most.
