Whats a good black primer to put on your parts soo they wont rust... i want one that will look smooth.. but one that i can put on without a paintin gun

[JJSZABO]

Go to eastwood and look at their rust convertor, rust encapsulator.  I used it and put it on my frame with a brush and spray bombs.

Here is a picture:



Good luck

What parts are we talking about?  Sheetmetal or frame pieces.
I personally wouldn't put a brushed on sealer on something I was going to have to sand later.
On a frame I recommend POR15.

Chris,

Not to start a debate about which is better, but I went with Eastwood because of their article on POR15 vs Rust converter - see:

http://www.eastwoodco.com/jump.jsp?itemID=852&itemType=CATEGORY&path=1%2C3%2C688%2C821&KickerID=173&KICKER

It's an article done by Larry Lyles.  Maybe just good advertising, but I bit.   Worked for my frame but I wouldn't use it on sheetmetal.  I was thinking of spraying in the crevices like the door interior and behind the rocker and cab corners.

Just my .02 worth. 

I am learning as I am going along.

I just read the article.  POR15 doesn't need to be reduced, it will spray through a gun just fine, reducing it in my opinion is a bad idea.  I painted the whole frame and all components with POR15 and it laid down fine and I am not a professional painter.  I have a skid plate that I painted back in 2000 that has been sitting in the dirt in my shop, it still isn't rusty.  As for sanding it, I couldn't scratch the pieces I painted with POR15 with a awl.  I had to jam a chisel in it to make a scratch.  As for cleaning, I clean everything with EZ-Off and wash it down with water and blow it off with air and let it dry.  Then I shoot POR15 directly on it.  I can say that it DEFINITELY is UV sensative, but I top coated ( within 2 hours while it was tacky) with enamel.  I used nothing special to clean the metal other than the above.

This is my frame with just POR15 on it:

This is topcoated:


This is my rearend right after I washed it down to let it dry:

This is about an hour later when I painted it with Gloss POR15:


I am not saying one is better than the other, I would use either as it doesn't matter with me.  I just know personally that in my experience POR15 works well.  I also didn't have them send me anything free either.  Now if Eastwood sees this post and sends me a free sample, I would gladly test them out....

Again, both are good products.  If you want to just paint and not topcoat and you like the color offered get the Rust Encapsulator, because if it is in the sun, POR15 will fade.

Nice looking frame Chris. 

Mike I hope we answered your question.

Good Luck

I guess I'm a believer in removing the rust versus encapsulating it with paint; sandblast, sand , primer and paint, but then again depends on what you are trying to accomplish. The frame does look good though, what year is the frame as it has a unique front cross member?

I have done it both ways. Sand blast works good as does POR 15 or Chassis Saver which is what I use. Its the same exact chemical make up as POR but about half the $. I have srayed it unreduced but works beter out of an HVLP gun with about 10% of the recomended reducer. POR and Chassis Saver will both work on sandblasted metal too. When I did my 55 I brushed Cassis Saver over the sanded surface rust on the roof. Can't sand blast sheet metal it will warp. Then I primed over it as I primed the whole car with high build urethane prime You would never know it was there.
Here is a picture of my buddies Duster, I used POR on the inside of the roof, then sprayed over it with acrylic enamel.

78BBSTEPSIDE - It's a 1986 C-10.  I sandblasted the whole frame before I put on Eastwoods rust converter.  The instructions said it could be used over rust or on bare metal.  Then over that I sprayed Eastwoods rust encapsulator and over that I put on Eastwoods Chassis Black.  It all came in a kit.  I liked it and would probably use again.  I live "close" to Eastwood and can have my stuff delivered next day without paying extra.  I would like to try POR15.

JJSZABO's frame is typical of a 80-87 frame that GM started lightening.
If removal of rust is an option, I would do it.  My whole frame was sandblasted:


My rearend was not as I didn't see a point in it.

As far as bare metal goes Sem makes a good self etching primer. You can Also etch the metal with Duponts 244S or = from another company before you spray anything on it. All the big paint companies make epoxy primers too. I use PPG's and Nason's most times because their cost isn't as high as the others and the quality is good. Nason's is made by Dupont.
