i should have all the welding and primer done this week just the boot floor to finish up
i have primed most of the underside already with upol #5 high build primer
i have sikaflex in a tube to use as seal sealer and upol brush seam sealer in a tin
what should i use on top of this before i spray the underside and put it back on the sub frames
gravitex has been mentioned on here is that best?
