Wouldn't the solvents in whatever sealant used to top a typical AIO remove the layer of protection left behind by the AIO? Even then, shouldn't the AIO be left to cure for certain amount of time [ideally like 12hrs] prior to topping? If that turns out to be true, then wouldn't people be fooling themselves when they think they're laying down additional protection over the weak protection of the AIO when in reality they're just winding up with 1 layer of protection not 2?
Btw, I'm not a believer in the topping of AIO's. I rarely even use them.
