Talking upol acid etch primer - how many use this stuff on bare metal?

how many of you use this on bare metal before stonechip? done a lot of my underside in this and i think its the best etch primer around to use! how has it lasted for you over the years?

Have used it in spray form many times with good results. One of the better etch primers on the market.
As with any primers the top coat needs to seal you cannot use this then a base coat for that factory look under bonnet etc as they will both be porous.

Best etch primers are the 2k epoxy primers which seal the metal.

i used the upol acid etch on bare metal (3 coats) then stonechip over it with upol raptor tintable, have heard of using the 2k epoxy, but im guessing acid etch is ok to use on the floorpan? well its been ok for a year or so
