i spent the last weekend blasting all the parts to my LV and then shot it with some high quality epoxy primer. but after looking at the primed pieces it looks to me like rust could begin forming at all the sheet metal joints all over the place before it gets final painted really well, which who knows how long that could take. is there any kind of chemical or seam sealer that i should try to put in the cracks or try to seal the cracks? if you look at all the new cars, all their joints are sealed with the body seam sealer. i realize that is suppose to be done just before paint so what can you do in the mean time to prevent rust from forming. i sure as heck don't want to have to sand blast again. sorry for the long post.
