after spraying about 3 coats of copper spray on a headgasket, is it best to install it right then or wait a good while for it to dry.

 

Let it dry so its sticky.

 

whats the point of the copper spray??? is it necessary or what?

 

its to fill in any imperfections in the head and block. I use it on every motor.

 

i see..well i just had my head resurfaced so i dont know if it will make a difference..but there is a chance the topof the block might so its probably a good idea...does it get all nasty stuck to the head or block if i have to remove the head again???

 

i put it on there sticky? like what, dry for an hour?

 

yeah dry for how long

 

kinda OT; but does anybody use hylomar instead?

 

hylomar ?
