cheapest place to buy I have found is normally EBay, and get ALL three things, the por-15 in black(color I recommend) there marine clean and the metal prep
and MAKE sure all things are SUPER dry before coating, any moisture on things will result in bubbles and exposed metal?
if you prep right, this stuff lasts a LONG time!
and a tip, any UN used POR-15, its air cure, so, you need to cover the paint with something to get rid of all air exposed to it
I used simple kitchen plastic wrap, place on top of paint and fill can like to sides and all and THEN put lid back on, it will keep a few months or so
but it will dry sooner or later on you due to well air cures it, so once you open the can, its already exposed!
if you have a few things you want to do, DO them all at once
any rust on your frame or?? on car or truck
good time to touch that up now too
IF you cover any NUTS or Bolts, they will be a LOT harder to remove, or even get a socket on in the future
NOT impossible, but this stuff drys like a weld will and a wire wheel will be laughed at for a bit when trying to get it off
an example here, I had some 50 lb tractor weights on a work bench when I was paint this stuff, so, for kicks I painted the weights some of the POR 15 ran down and touched the bench top, not a LOT either
I left them there for a few weeks,
one day went to move them back on tractor
and the dam things were stuck to that bench, I needed a 4 ft pry bar to break them free, and only a few drops was holding them on !
DO NOT get this stuff on your fingers and hold them together for long, they will NOT come apart LOL
and if you get this stuff on you, and DON"T remove it with a good solvent FAST,
it AIN"T coming off for weeks or more!
its crazy how this stuff bonds things and sticks
I wish it wasn't as costly as it is,/cures after opening!
as I would paint a LOT more things with it
I have used to to hold things together too, on my skid steer, rubber vibration pads between things kept coming off, with construction adhesive and calking s/silicone and stuff
I used this stuff as was painting something one day just to see, and its NOT designed for this either LOL
and it has never come off since , its like welding with liquid here
