Recrudescent Magic
Your spells can resume even after being dispelled.
Prerequisites: Extend Spell, Heighten Spell, Spellcraft 11 ranks
Benefit: Choose one spell you are capable of casting, which must be one level lower than the highest-level spell you are capable of casting in that class and cannot have a duration of concentration or instantaneous. Whenever an instance of that spell that you personally cast is dispelled (but not counterspelled) by dispel magic, erase, greater dispel magic, or a similar effect (but not break enchantment, dispel evil, limited wish, mage's disjunction, miracle, remove curse, wish, or a similar effect), it is instead suppressed (as if by Aroden's spellbane) for a number of rounds equal to 3 + the amount by which the dispel check exceeded the DC, if any. After this time, the spell effect returns, provided it has any remaining duration. While suppressed, the spell effect radiates a dim aura of magic and can be identified via divinations and similar effects.

I'd suggest changing it to Recrudescent Spell, as a +2 metamagic feat. +1 might seem well high enough, but dispel was deliberately weakened in Pathfinder - it shouldn't be countered too easily. Being able to keep your mage armor, etc., from being lost can be quite useful.
Agree with blahpers - if you're using this for one specific spell, it's probably something really annoying.
Interesting that the original suggestion is 90% equivalent to an Epic feat.

As a metamagic feat this becomes "Protect Permanent Enhancements". Any spell you'd cast with Permanency with would be metamagicked with this. I am not sure that makes it worth taking, I guess if your DM slings a lot of dispels against you it protects an investment, but ultimately I am not sure it'd be worth the feat in any event. If a DM focused on dispelling, I'd never spend the money to make anything permanent.

^Which brings up that Permanancy seems as ad-hoc'ed ms in 1st Edition. Now (actually as of 3rd Edition) that it isn't needed for creating permanent magic items, I'd like to see it rebuilt into a Magic Item Creation Feat (except instead of creating a magic item, you create a Permanent Spell). You could apply a Metamagic Feat (including the Metamagic version of Recrudescent Magic) to a spell to make permanent, but with the rebuild using more or less the standard Magic Item Creation rules, it would be more expensive, and also more of a pain if you NEEDED to dispel a Permanent Spell to free up an item slot for a different one.
