POR-15 good or bad?

[coxie1996]

ive been looking into POR-15 lately, my engine bay is almost done getting sandblasted, then using red scotch brite pads on it all and self-etching primer, then scotch brite it again. then POR-15's black cote, and satin clear.. i heard there paint is super tough, and if done right looks super. but i've searched the threads and some say "go for it!" others say "stay away from it"..  im not going with a gloss finish on my engine bay but not flat either.. satin seems best. just need some help figuring this out

I really like it used it on my 69 brushed it on and it looks like it was sprayed on.

I think right on the can of POR-15 it say's do not apply to sandblasted metal. LEON.

if youve got pitting. use some extend rust killer. let dry and epoxy and prime right over it . I live where it rains 200 inches a year and it works great

Worked for me.  Make sure you follow their directions and use their cleaner and ready-prep.

Paint your egine bay the color of the car. POR is fine in other places that does not see the sun.

I've used it. It is good if your prep is done correctly. It is not a rust cure-all "miracle", but it does have it's place.
POR-15 likes a substrate that is roughened up, that is why they say it is OK to put directly over rust. Clean sandblasted metal is also a good choice, as the surface will be rough from sandblasting. It does NOT like to stick to smooth, clean metal surfaces.

I used it on the underside of my car after sandblasting (like yourself, I was on a tight budget), & so far it has held up very well. POR-15 also makes a self-etching primer, that is designed to go over cured POR-15 and enables you to apply whatever topcoat (paint) you want. After coating the underside with POR-15, my car sat for almost a year while I was doing other bodywork. When it came time to paint the underside, I sprayed it with their Self-Etching primer, then used urethane paint over that. Everything has stuck very well, even did a blow gun & duct tape test.

Read their tech sheets very carefully, and follow them if you choose to use their products. I'm leery of putting anything over rust, so clean the area well (grinder, wire wheel, etc).
It is relatively inexpensive, but you will have to topcoat it with something as it does not hold up well to UV.

i swear ive heard that 100 times........ my car is burnt orange and black.. hood/ front is black and the engine bay would look out of place if painted burnt orange.. im going with satin black which will match the exterior.. and thank you guys i found some cheaper stuff at a local farm and home(2 HOURS LOOKING AT PAINT LOL) and found it better i UV protection, color and strength.. thanks so much guyys!!

rightly said. ppl think they just put por over and leave it . it will disinigrate ovr time  you must top coat it like you said. and read their sheets ..

I don't like it.  If you don't prep properly it will flake off in sheets.  You have to use metal ready, and the proper substrate.

I like epoxy and paint. Proven technology that lasts forever with no guesswork.  Por15 can look perfect and after 6 months, just flake off.  Not reliable! 

Masterseries CT is a better anti-rust product.  It sticks to anything and it won't flake.

Fingernail polish remover. It comes right off.

Correction, I guess you can use this over sandblated metal. I must be thinking of Eastwoods rust ecapsulter or some other product. LEON.
