por15

[onelow84]

ok so I have my frame, control arms and everything sandblasted and am getting ready por15 it all. Is two coats really necessary? how long should I wait to put on a second coat? Any tips besides being careful not to get it on my skin? I read the instructions a couple times but just want to be sure. has anyone used this stuff on tie rod ends/ adjusting sleeves? also curious if it be ok to spray the frame down with a multi purpose solvent like brake clean. any help would be appreciated!

i think multiple coats are good. i recently painted my frame and underbody with 1 coat and rust is coming through after just a couple of months. i also sandblasted. while you are putting the effort in , might as well do it thoroughly.

Really with anything, more than one coat, (at least 2 coats)  is to prevent you from missing any spots.  No matter how simple a job may seem, spots can be missed.  at least 2 coats helps make sure everything has at least one coat on it.  I'd go 2 coats minimum on something that's purpose is protection.

I always put 2 coats on, and I spray it straight out of the can.

can you get it all out the gun or do you buy cheap guns and then trash them? should I avoid getting any on the threads? (shock mounting bolts, tie rod ends etc) I will post pics this weekend. I am doing the frame in semi gloss black and doing my control arms with silver chassis saver. Thanks for all the help!

Yeah, I bought a cheap gun but it can be cleaned.  I usually fill the gun up with lacquer thinner and spray it through the gun twice.  I used one for a while until someone borrowed it...

Now much will a gallon do.   Would it do an entire truck frame?  Axles and leaf springs?   How far will a gallon go without being spread too thin?

I sprayed my frame with 2 coats and used less than a quart...makes me sick I bought a whole gallon.oh well I think I am goona find a bunch of uses for it to use it up on my project. I am thinking of spraying the inside of my doors and such. If you spray make sure you use a respirator because this stuff is nasty!

Yes stay away from threads with it.

Quart did my all the pieces on my rolling frame and then some.
DEFINITELY Get a respirator.

I'm currently restoring a 73 Chevy shortbed.  My plan is to thoroughly clean the entire truck of grease and oils along with the old paint and bondo.  I have Marine Clean and metal ready.  Has anyone seen any great success with the Marine clean?  I've used Marine clean before but I didn't think it did such a great job.  I've also tried POR Strip but it didn't seem to take the paint off as good as Tal Strip.

What is the best thing to completely clean and degrease a truck?
Also, should I use metal ready on the body before applying the POR15?

Just looking for some experience from others who are familiar with POR15 products and how reliable they are.

[Captkaos]

are you talking about the sheetmetal or the frame?

[onelow84]

I would guess body if he is talking about bondo

[Captkaos]

I wouldn't paint sheetmetal with it.

A good 3/4 of the roof on my 55 was covered with surface rust. I sanded as much off as I could with 80, then 180 grit paper on a DA. Then I rolled Chassis Saver over the rust, waited about an hour, and sprayed Transtars High Build urethane primer over it. Sanded that with 320, and sprayed Omni single stage for a top coat. Its been about 6 years and nothing coming through yet.
