Yes! I do offer a premium service which uses Polymer capacitors. Polymer capacitors will never leak this is due to the polymer that is used once manufactured the liquid polymer will become a solid within a few hours hence why it will never leak as there is no liquid!
Traditional electrolytic capacitors has a liquid and hence prone to leaking as they age. However I use a good brand of capacitor and always use Panasonic or if I’m able to source it will be another trusted brand so these will still be good for 20 plus years. But polymer ones will last a lifetime.
Now some recappers use Tantalum capacitors, these are solid and used else where in the Amiga, however these are NOT suitable replacements for the electrolytic ones check out why in a separate FAQ.
