painting the frame
 

just got my new "stretch " rails for my knight hauler..i want to assemble as much of it as possible and paint it..my question is would "scuffing " the black plastic parts be enough and the shoot with primerand the paint.. i dont think the plastic is flexible enough to crack the paint:confused:

Re: painting the frame
 

I always wash with degreaser to make sure the mold release is gone, fine sand and prime. I also prefer to paint assemblies but that is just preference.

Re: painting the frame
 

The last time I painted an assembled chassis I used self etching primer. The paint stuck extremely well and I did not scuff anything, the thing I did not like is the paint looked to thick to me.

i think i am going to assemble the whole frame and suspension and paint as one...i am in the process of re-fitting all the components to the new rails..(finding out some holes are not the same diameter and 2 so far are missing)..:mad:

Paul, just a hint, you do not want to use dish soap or any other liquid soap that is meant to be used where contact with a humans hands is likely.. They have lanolin in them and that will cause fish eye's in the paint job.

Just an FYI

Right I know that one step ahead of you there I ran a body shop for a number of years there are still soaps out there that are good old fission hard on your skin soaps.. Plus I never paint anything with out wiping with prep solvent before i spray any primer. LOL not my first rodeo I spray for a living everyday. Greg I also use red scotch bright but if you are not washing or using a final prep before primer you will have issues just wait just like using that crap squad puddy or real bondo brand body filler it you are not buying quality filler you will have issues there are only 2 company's in the about body world that make filler that they warranty against shrinking 100% read close I see a lot of guys making this mistake also.

whats the difference from a red scotch bright and a green? does it matter?

Re: painting the frame
 

The green I think is coarser. The gray is ultra fine, this is what I use .

No problem Paul, I am sure you have painted enough stuff just in this hobby, I just made it clear for someone that might not know and was reading your post.
You did say that you was it down with dish soap or a prep from a body shop. I know you meant "and" instead of "or" but someone that has little to no experience painting might not...

Wasn't trying to correct you, just giving some helpful information..

Mike, If you get some Prepsol or any other wax and grease remover, this is what you want. You can even get the stuff at Auto Zone or any auto parts place.
