On son's 63 Monterey... we're not able to to a frame off, but I need to put something on the frame after the usual time- spent-on-your-back-under-it scrape-fest!

anybody got a product that you've used and liked the results from?

looking for, in no particular order,

-expense

-effectiveness on containing/mitigating rust on frame

-ease of application (we're set up for brush-on only)

-availability

appreciate any first-hand recommendations that you'd care to share.

In my opinion Por 15 is the best thing on the market for your job.  It's specifically designed for rusty metal and will cover rust very well.  It is quiet expensive at about $50 a quart but well worth it.  Just Google Por 15 and you can learn all about it.

Rust Bullet....overcoated with their Black Shell. Can be applied over solid rust with a brush...looks great and last forever! Beats POR15 with a stick. You can also look into one called Master Series, I believe it is the same stuff but cheaper. Basically it is an industrial Poly used on bridges and well rigs that has found it's way to the car restoration group. It does just what it says it will. ONLY rust paint I've ever found that I felt did what it was supposed to. Not to put POR 15 down but this stuff works with far less prep than the POR15 and in that sense becomes more economical.

I have never used POR-15 so I cannot compare them but I have used Rust Bullet http://bit.ly/rtmMUo with good results as I stated in your other thread on this question.

I used POR-15 and very happy with it. It really does not need a lot of prep - just make sure any oil or grease is removed (you can use lacquer thinner, denatured alcohol), wire brush the area to remove any loose rust and paint.

I've used POR 15 on many projects, including the frame on my T-bird.  I did the frame many years ago and it still looks great.  It's easy to use  ---but be sure to wear gloves as it sticks to skin very well too---- and not all that expensive when you think about what it does.  Based on my esperience, I recommend it.

I have also had good success with POR15. Use throw away burshes and wear gloves. As stated, make sure it is clean and no grease.

just a word of caution bearing in mind you said you would be using brushes

i sprayed POR-15 on the underside of my truck and ended up with the local medicine man!

i had a pressurised hood but rolled onto the air feed and some how breathed some in. its not good and medicine man just rolled his eyes and said " there's nothing i can do" he had two others (professional sprayers) on his books and the best he could do was help with compensation claims.  i survived ok but it did scare me

good luck and be careful

i haven't used it on frame but did the whole floor board in my 54. with por-15 i was very pleased with the results,i went with the brush/roller method. like stated above make sure any loose rust or debris is removed and use disposable tools.

I know of at least two POR 15 dealers in the Houston area. Don't know if this one is handy for you, but it is where I buy mine. They are in Waller, TX out toward Hempstead. It is right on my way into Houston on Hwy 6.

Most of the POR 15 brush jobs will blend together and look like spray painting. I really like it.

well, Waller is quite a holler from my end of town.  May go with a test of the Rust Bullet product... that is, when I have scraped about 75 more lbs of gunk, rust, grease and dirt off the frame of the car...

hey, wait a minute... this is son's first car... HE will be doing all the scraping!!

thanks to all for the suggestions... hopefully will post some pics of the process soon; right now its mostly greasey... and nobody wants to see greasey, right??!!

I just finished doing the samething to my '58 Custom 300. Here's the results:

I would also recommend the Por-15 stuff. It does stand for Paint-Over-Rust anyhow. BigGrin

When I was searching for a gas tank sealer product, I found a company called KBS coatings. I have been using a product called rust seal, with excellent results.The stuff comes in different colors, about 44$ a quart. They recommend a water based cleaner, and an etch product, but I have used it right on rusty metal, and it bonds well. If you buy this stuff or por 15, rust bullet, stop at your local paint store and buy an empty can, pour 1/2 of it in there. These cans are hard to re-open after a couple of use's. Put a sheet of plastic over the can when you put the lid on. Check out their website, they also have engine paint, heat paint, lots of good stuff, super fast shipping

tried some KBS on a small section of the car's trunk; followed all 3 steps; works well, but I'm looking for a "one step" product if I can find one... so far, looks like its RustBullet or POR...

another vote for POR-15, it self-levels and looks really nice, almost like powder-coat, here is a thread from another build with some pics

I used the degreaser and the acid wash from POR-15 as well before I put on the paint, since then I've used other degreasers to get the grease off before painting and as long as you get the grease off it works great, very durable and flexible.

Just another comment on the KBS rust seal, I've tried it as a one step and a 3- step. Works fine either way, I think manufactures try to make sure you have a good clean surface so you get a good bond. As long as its clean, you can brush the rust seal on like por 15. The rust blast (step 2) is kind of a primer in a spray bottle, I use it, no big deal.
