Spray POR-15 inside frame?

after 4 months now of looking into all the various coatings i have found several bad reviews on the POR-15 stuff and i don't know why because everybody seems to keep saying its so great!

i found a video demonstrating the Eastwood encapsulator platinum which requires not much prep work (already built in) and is fairly UV resistant i think. the Only 'problem' is its a silverly finish so you probably need to put black topcoat on it anyways and it may have been biased being produced in the Eastwood tech studio

they did a super salt spray test against the leading competitors with a big scratch to demonstrate chips. The other leading competitors did not fair so well in this test at all. But I am not sure which brands they were because they were all anonymous

maybe have to do my own testing with some chunk of frame from the junk yard unless there is a proven TW experiment on this already, so far i have not found very much in the archives

 

por15 is good stuff but it needs a rough surface to stick to or it flakes off. I just started using lanolin this fall to undercoat with i bought a gallon of fluid film and did my 4runner then i bought a gallon of WoolWax to do my Tacoma. I can say that the WoolWax is the better product it is much sticker and i can tell that it will not wash off as easy. The texture of both products are much different. The Fluid Film has a weird jello consistency and it says to stir it to break it up and get it to flow. I never had any problems spraying it but it just looks weird. WoolWax looks more like butterscotch pudding. It dont spray as easy and it is a bit harder to work with because of this but it is so sticky you know it will hold up much better.

The bad part is that you cant spray it though the 32" long 360* wands because it is too sticky. When i spray inside my rockers i use bar and chain oil because it sprays well out of the 32" wand and it's not going to get on rubber and harm it anyways. Fluid Film sprays out of a 32" 360* wand but not as well as bar and chain oil. So now after spraying a wide verity of stuff i use woolwax and bar and chain oil i dont even bother with Fluid Film.

 

Probably 99% of people’s POR15 testimony is directly after application. You won’t find many long term reviews.

Most testimony is in off-road communities. The car restoration guys though spit on the stuff.

It’s fine as a last ditch effort product or application on a beater. Otherwise anything not in those 2 categories I’d pick something else like plain old wire wheeling the rust and rattle can followed by a rust protectant (for example fluid film)
