Re: need primer advice

Let's think about it another way. Think about the surface of an orange. Have you ever seen a shiney orange ?

There are high spots and low spots... just like the surface of your truck. The idea behind a good, straight and Shiney paint job is one thing. If it's not flat.. it will not shine very well. A rough surface just doesn't shine like it's wet.. (like you would want your car paint to look)

So, you asked about how to know when to stop sanding. When the high spots become level with the low spots. If the highs are high.. and you're sanding flat that's what will show up back when you sand through your primer.

That's why you want to use the guide coat. Guide coat will fill the low spots so as you sand you'll begin to see the lows.. then your high spots either blow through to the epoxy or even metal worst case.

The next step is sealer. Once the truck is flat and you have all the lows UP and the highs DOWN.. regardless of what color it is your sealer makes everything the same uniform color.

The paint job will only look as good as what's underneath it.

Take your time.

Re: need primer advice

thought I would update this. I stated with epoxy primer then I used high buid primer with a lot of sanding between. I have waited a long timedoing other projects but now I am back on this one.truck got all dirty sitting outside so I sanded it again and sprayed It with some more high build. I did practice paint job on another truck with single stage so now I am ready to paint this one . still not sure what kind of paint I will use but I am thinking single stage.

Re: need primer advice

thought I would update this. I have decided to paint it my self again. I did paint the cab of another truck gold. I used single stage paint. this one will be 2 stage because the single makes it too hard for a rookie to fix any mistakes. I have sanded truck then used epoxy primer. sanded it and used high build primer. sanded again and used high build again. now as soon as I figure out which color I will start again. looking for a light blue non metallic.i will add pictures of before and now and the gold I painted.

Re: need primer advice

I usually use either a green scotch brite pad or 220 paper to knock the epoxy down right before the first coat of 2k primer. (High build) There's not really any need to sand the epoxy primer before 2k primer as long as it doesn't pass the 7 day window.

* Bare metal - 80 grit scratches.
*Fix any metal issues (dolly or filler, however you choose) make sure all areas wherr youve pit filler are sanded to at minimum of 80 grit
* Epoxy prime, 2 coats. I use Southern Polyurethanes and I'm very happy with it
* knock the epoxy down with scotch brite or 220 once it dries
* 2k primer - first coat
* guide coat
* block with 320
* fix any metal issues, low or high spots
* 2k primer - second coat
* guide coat
* block again with 500 if you're doing single stage, or solid color base / clear

* for metallics - one more coat of 2k primer and block again with 600. Metallics will lay into the sand scratches at about 400-500. I usually go to 600.

Base and clear to your liking.

I personally like single stage but I like blocking too,.. so.

This caught my interest. I'd like to hear why, I think I know the answer, just need to hear it from someone else.
