painting the frame question

[scotty101]

I plan on sandblastin my frame this weekend and am then planning on puttin on a coat or two of rust encapsulator from eastwood. is this stuff hard enough that i do not have to put a coat of paint on it or will it just chip away? a question with sandblastin do i have to cover the rear end, suspension or the front steerin linkage?

[Srubydo1986]

no but you might want tpo clean everything real good when finish sandblasting also cover the engine from undernieth so no sand goes past the oil pan and up. as well as the transmission.

I'd go with POR-15, myself. That stuff is tough as nails and looks twice as good.

I did some test pieces on my frame this spring with Rust Encapsulator. You absolutely do not want to use it on untreated bare metal or you will get rust creep within a month or so. On another section, I laid it atop a coat of Krylon rattlecan primer and haven't seen a hint of creep yet. If you really want it to stick, use Eastwood's $99 chassis coating kit with a 2-part rust converter.

I've also used POR-15 with good results painting directly to rusty metal, just knocking the scale off. That car later became one of very few 80's G-Body frames to survive 20+ years of Maine winters.

so rust encapsulator will not hold to a sand blasted frame? will por 15?

[Blackstone]

I didn't blast my test pieces, so there was a bit of rust left behind when I painted. Adhesion wasn't a problem to bare metal, but the surface wasn't completely sealed by the Rust Encapsulator alone. Within a couple weeks, rust began to creep out around seams and rivets. The next time I do it, I'll sandblast the frame, then use either Rust Converter or self-etching primer on the bare metal followed by Rust Encapsulator, then a "chassis black" topcoat.

Long story short... Whether it be POR-15 or Eastwood, it's best to use all recommended components in their system.

Here's a 2003 article featuring a side-by-side test:http://www.eastwoodco.com/jump.jsp?i...rID=173&KICKER

I switched from POR-15 to NoRust. NoRust I think looks better. POR-15 with time will fad. Checkout the suspension pictures I have in my signature. I used POR-15 on the a-arms. I'm using NoRust on everthing else.

[scotty101]

do you have to paint over this no rust stuff or is it a stand alone deal? do i have to lay a coat of primer on before using it? where did you pick it up at? thanks

I have used por-15 and I have also used Imron. The por-15 does fade and is a 3or4 step paint. Imron is a 2 stage and can be applied directly to bare metal. Imron 2.8, is available in high gloss and flat but is costly to get in colors other than black and red. Imron is an industrial type coating that seems to be almost like powder coating. I use my primering gun though, because it is soo thick it will not run thru a finishing gun. I use imron on lots of applications outside automotive and I like it the best.

POR-15 can be brushed on with a foam or cheap bristle brush. If you use the gloss POR-15, it will look like powder coating when dry. The down side is, according to their directions, it will fade out if exposed to UV rays. You can top coat it with their chassis black top coat. POR-15 seems to be very tough. However, I only just applied it on my 77 so I don't have any long term comments to pass along. I would hit the frame enough to clean all loose stuff off with a light sanding using one of those sanding sponges from 3M and some water. Let dry overnite and go after it. I'm painting my frame little by little with left over POR-15 from other projects on the truck to keep from wasting it: $25 a pint! I'll attach a shot of the behind the grille area on my 77 Bonanza. You can also see the frame horns sticking out. I just cleaned them up a bit and painted them with POR-15 gloss black. Same with the roll bar. I changed over to semi gloss black after I used the pint of gloss, but don't like it as well: doesn't flow like the gloss and seems to be harder to get looking good with a brush. The next can will be gloss.

I painted my frame with POR15 and then top coated it with Black enamel after the paint had become tacky. Holds up pretty well and isn't UV sensative.

These parts didn't recieve the topcoat.

I used this stuff, very sinilar to POR15 (only cheaper) and they have UV and non-UV resistance stuff. www.nomorerust.com Came out "like powdercoat" too and I only used a foam brush....

[scotty101]

well i plan on using an air gun to apply it and am still leaning to rust encapsulator, but i just want to make sure that i order everything i need so that i am not waitin to start assembling bc i had to go back and order more stuff. so how much should i order to cover my whole frame and the under body of my bed and cab?

[msgross]

I would ask Eastwood... I brushed mine on and didn't even use 2 quarts but that's no overspray...

that's what I used but it isn't UV friendly. I would use the other stuff they have and the sealer. That sealer is awesome stuff. Great coverage and should be used on blasted metal. I would buy 2 qts of each and he'll make you a good deal on price. $100 does it all... Once this stuff dries it's like powdercoat and resists everything...

[scotty101]

msgross would you link me to the "other' stuff you are refering to. or are you talking about there silver primer stuff?

[msgross]

this comes in satin or gloss... you can mix a little or a lot. Key thing with these urathane paints (por-15 etc..) when you open the can then the clock begins, it will last for awhile in the can but it cures with the moisture in the air. Never buy it by the gallon....

[scotty101]

so would the kit they offer be enough to do a whole frame? or do i have to order two or just add another quart of the top coat?

[msgross]

maybe just a plain frame. If you also want to do axles, springs or a longhorn then I would get two sets.

[Captkaos]

Just to let you know, I spray POR15 on all through a gun.

[scotty101]

well i ordered two of there frame kits of ag111. they gave me a discount on it which was quite nice. although shippin is going to be spendy. from new jersey to minn. so thank you all for the help and opinions i will report what i think of it.

[msgross]

cool, send pics. You could always resell any unopened cans...

Be sure to have a well ventilated area while brushing on Por15. Use a Organic vapor particulate respirator when spraying POR-15!

and use some good rubber gloves and long sleeves, it WON'T come off skin easily and it won't come out of clothes.
