Hi:
I have a 1995 Toyota pickup that I just bought a rust fee box for. I am in Canada and this box came from "Georgia USA" almost 1800 miles to get to me. I want to keep it rust free. I want to coat the bottom in POR 15. My question is do I need to use the POR-15 Metal Prep first? I am also going to do my frame while I have the old box off.

Would I por 15 the diff case and axles and fuel tank and transmission or just the frame?

Would I need a whole gallon to do the frame and bottom of box I hear it spreads on really good and does not use a lot.

Thanks for your reply.

I would not use that stuff again. It is good for a little while but once it starts to lift off all the water and crap gets under and rust eats faster. I have found the best thing to do is make sure that it is painted well (repaint underneath) then undercoat with come kind of oil based rust protection every year ( I like Fluid Film but very expensive). Like soak the hell out of it, same with the frame and axles.
I too live in salty Ontario and there is not much you can do if you drive in the winter except oil, oil, oil.

rust free box? In my bodyshop I've changed box sides on new trucks with 5000km and they already have rust starting.

anyways, do what flash said and repaint the underside of the box then hose on undercoating...and reapply it every year. Make sure you get lots of undercoating above the wheel well. Every crease and creavase you can undercoat...do it.

a wax based undercoating sprayed through a wand would be prefered way to start, then let it sit for a day and creep into all the little gaps, inbetween all the spot welds ect then hose on your typical black undercoating.

+ 1 For the Fluid Film. The salt here in Ontario is outrageous. I would bet that it is the worst place in the world for corrosion issues.

Please take care of your new bed, don't let the salt get it!

Thanks for all the replies guys!

I have used Fluid Film on my truck before, I wish the first owner used it all its life

I think that's the route I'm going to go. Just do the fluid film 2 times a year. I love the stuff it get into all the cracks and nooks and inside the frame all the suspension etc...

My new box is sweet and rust free and I plan on doing the best I can to keep it that way.

What did you pay (total with shipping) for that box? I think I am going to go fiberglass once my current one falls off.... I'll be checking with you Slacker.

I got a fiberglass box from Slacker a couple of years ago and am super happy with it. Really good attention to detail and the body shop doing the paint work gave it really good reviews.

Now if we can only get him to make fiberglass rockers and cab corners!

I paid $1000.00 for the box. I got a good deal on it most times a box in that good of shape sells for $1500.00 or so.

Fiberglass would be sweet but out of my price range
