I absolutly love primer mobiles, and I'd like to keep mine that way (there isn't much more body work left!). That, and the fact that I don't want to pay for a nice paint job (if I get it painted, I want it top quality!)

A friend of mine has a paint gun, and I believe he said he would primer it for me again (all one color!), and once I do that, I would like to keep it looking nice. Primer seems to get "stained" with dark marks (as well as scratches!) and doesn't clean up to well.

Is there some sort of additive that can be mixed with primer to project it from stains and scratches? it scratches quite easy :-\ I asked some hotrodders who own hotrods that are black primer (TOTALY sick!!), and they said that to keep it from scratching, dont' scratch it (basicly, show cars... I guess)

I have been primered for almost 6 months now, and the GFX hasn't started to crack yet, so I assume that primer needs no flex additive for the urethane parts? or have I just been lucky?

Any particular brand/type of primer that would be best? Or does it really matter, because there isn't going to be any paint on top of it.

Thanks!

I was told that flex additive needs to be added to the primer and the clearcoat on urethane parts.

And also, primer absorbs moisture. Maybe you should clear coat the primer? Or are you trying to keep the dull look?

I'm gonna move this to the Body board, cause its more Body related and you might get more help over there. Good luck

 

I would use an epoxy primer for you application. Many of your urethane or polyester based primers will absorb moisture. Epoxy primer is just that...epoxy...good, tough stuff. What color primer do you want? Epoxy should not absorb moisture..

 

ahh, sorry about that

yes, I want to keep the dull look, want it to look just like primer, only with out the stains and scratches that form over time (weeks)

or is there a flat paint that could be sprayed on that will have no shine at all, and not scratch?

 

I'd like it to be light grey, just like primer :-)

epoxy primer eh? I'll look into that! thanks!

 

you can add a flattening or satin agent to any paint to cause it to get that flat primer look and it's totally protected from the weather

 

is the flattening/satin agen expensive?

so, just start mix that with silver or a grey paint, just a normal paint? use epoxy primer under that, or will any primer do?

 

You could use flat rustoleum. Won't scratch easily, won't stain, resists rust, and will last a long time. You could probably buy a can and thin it out so you can spray it with a gun.

how would I thin it out?

Is there any choice of colors?

 

you could use a flattening agent, but you would spend alot more $$$ than if you just used epoxy primer. Use Omni (PPG) MP170 epoxy primer with a mp175 hardner and you can reduce it up to 20% with a omni reducer.

 

flattening agent is not in itself very expensive but when you are considering that you are actually going through the whole process of painting your car it adds up you need primer, sealer, flex agent, paint, and so on because you use it just like a regular paint job

 

hm... well I was trying to get out of the expense of a full paint job. I honestly like primer better, it just happens to be cheaper. I grew up with primered hotrods with everything stripped off that wasn't needed, I guess thats where I'm coming from.

So, in light of these options, which would be cheapest? My friend has a paint gun, and I assume a paint gun can shoot any of this stuff? or is a special gun required?

 

if you're going with bang for the buck go with the epoxy primer

 

so, for the epoxy primer, should I sand all of the old primer off?

The rattle can primer is only on the front nose, the rest of the car is "normal" primer shot from a paint gun.

Or just lightly sand the primer and spray the epoxy on top of that?

I read somewhere that epoxy primer needs a coat of something on top of it, is this true?

what brand epoxy primer is best?


Thanks again guys!

 

1) sand off all the old rattlecan primer.... scuff the rest

2) i don't know for sure but i don't think so

3) any name brand paint will have a good epoxy primer can't go wrong with sikkens dupont ppg ect.

 

thanks so much!

So this that I heard about having to put another coat of something over epoxy primers, is that not true?

and another question ( ) should the epoxy primer hold up good on the urethane? or will some flex agent (or whatever) need to be added?

 

you will not need to add any flex agent. Epoxy acts like a sealer, it "seals" the car. You do not have to put anything over it. If you ever want to repaint the car, you will have to scuff th epoxy and re-epoxy it and then paint the car within a couple of days because of chemical adhesion.

 

hey, it sounds like we have a winner!

So, how much option in color do I have? I want a grey color, medium, a bit darker than what mine is now, like the color of the front nose (the rattle can crap)



possibly a little darker, and not so blueish looking (it looks a little bit blue in person, maybe thats just the light from the sky)

and, to wash the car, just wash like normal? water and carwash soap, and a spong? or would a stiff bristle brush be better?

 

use the stuff I told you to and it will be a tillt darker than the rattle can. wash it like you would normally

 

so strait epoxy primer should be a bit darker? Nice!

Thanks so much!

 

Wow, haven't heard this kind of thing in a while. As some of the old hot rodders used to say, "If it's in primer, it's not finished- and a hot rod should never be finished".

 

haha, thats a good little quote! I like it!
