Would be an interesting test, but I'm with Hazcat, it might not do you any good. I'm curious to see if anything can even bond properly overtop at least the latest formula of Reload, considering the level of ineffectiveness many very harsh cleaners have in removing its bond. I guess it depends on how long Reload's been on the paint, but at that point I might just reapply some more Reload to the paint and call it a day rather than mixing products.
