Primer

[btceng]

Thanks again. I'll post some pics soon on the progress. I want to get it primed first.

So, it's been a couple of weeks and I've got it down to clean metal on the front clip. Do I prime first with the epoxy primer or go ahead and apply the filler to my repair areas?

I think that it should be primed for protection and then do the bodywork. Filler needs to be applied to clean bare metal right?

IF you're using epoxy you can do it either way. You can lay down the epoxy and fill over top of it after you've given it a good curing time.

Thanks ramenth. I am an absolute novice but things have been going well so far. I'm a little intimidated by the painting but it's all a learning experience.

Don't be intimidated, ain't nothing that can't be fixed. I applaud you btceng for doing it yourself, and wanting to learn.

I agree. You're willingness to learn shows that you're willing to learn from any mistakes you make, too. Go to it and remember to have fun with it!

I've said it before.............ain't scared of trying, only failing. That's where you guys come in. Thanks for the help!

Shh, don't tell anyone this...

but failure is always an option. If your ain't succeedin' or failin' it means you ain't tryin' and it means you ain't learnin'.

As for the help, it's our pleasure.

 

[btceng]

Okay ramenth, the failure option reared it's ugly face. I have sprayee primer with no problems and finally purchased a half a pint of Tor-red to get a look at both the color and my ability to lay down a quality finish. I have obviously got a water problem. I have a filter and a water separator as well as one of those last chance filters at the gun. The paint would have been fine if not for the multitude of fisheyes. Base is not kind. It was my old hood, so only a learning process.

 

[btceng]

Here's the evidence. Embarassing.

 

[ramenth]

Fisheye ain't a water issue, it's an oil issue. Did you wipe it good with wax and grease remove before you sanded and again before you painted it?

 

[btceng]

I did. I sis not do a super job because it was really just a test. I did think about the fact that just before I sprayed it (15 minutes or so) it got sprinkled with water. I only wiped it down with a clean rag then sprayed it.

My setup is a little odd because of some space limitations. I have a 60 gallon compressor that runs through a transmission oil cooler then to a can type filter (cheap one from HF) then through another 3/8" filter/regulator then the hose to my gun. There is a disposable filter at the gun. I have had a problem with water and I guess oil. The humidity and heat here along with the run times of my compressor causes a lot of condensation in my tank and lines. I used the oil cooler as a makeshift condenser. I got that idea from another forum. It did seem to help with the air tools. I have not seen the issue with primer, although, I am famous for orange peel. Getting better, though.

My paint coverage was good and the peel wasn't too bad for me, but the fish eyes are just crazy.

What takes care of the oil issue? I would think that at least one of those filters would catch it.

 

[ramenth]

Got a question for you. How long did you lay the primer on before you laid the base?

 

[btceng]

You're going to be disappointed but since I was going for a color sample and a test spray, I only scuffed the old finish with 320 and washed, then dried, then w&g remover, dry, then spray. Is is possible that the w&g solvent base caused the issue by me not totally removing it or maybe rushing the process? I thought that I was careful to thoroughly dry it. Again, I wasn't really going for a long term paint job but I hoped for a nice spray.

 

[ramenth]

So you did a quick spray over the original finish?

 

[btceng]

Yes. I was really most interested in showing my wife the beautiful Tor-red.

 

[ramenth]

Then don't worry about rather or not you got fisheye if that's all you did.

How many years of wax jobs was on that hood? How many years of road film and oils? And you just did a quick hit with sandpaper before wax and grease remover... the sanding just worked it all in and spread it around. Yes, I know you washed it first, but that doesn't get everything off. Hell, even the soap could have a small amount of silicone in it that you hit with the sandpaper. Then you put base on top of decades old acrylic enamel. I could go on, but I think you get the picture of what happened.

In other words, don't panic about this particular piece. You want to experiment some more get a piece of scrap you have laying around and properly prep it. I'll guarantee your results will come out different.

 

[btceng]

I hope that you are correct. That experiment cost about $30, but the lesson is more valuable. I learned a lot about cleaning. As dead as the paint was on that hood, I thought that the sanding and cleaning would have been sufficient to see a quality appearing top coat. I knew that the foundation under the top coat was grossly inadequate. I guess I should have at least hit it with a coat of primer first. I didn't want to have to sand the primer.

I would have to agree with ramenth on this. Sometimes wax & grease remover doesn't always do the job with just one application. With the PPG paint line there are two different wax & grease remover's, DX 330 and DX 440. I opt to use the 440 because it is a little stronger, so you gotta be careful if you use it on fresh paint. Just my 2 cents.

 

[btceng]

Good to hear from you Alley. What model and brand gun do you guys recommend for spraying base/clear along with tip size? I just have one of those Chinese 3 piece sets that does a good job on primer but not sure that I it or myself for the base/clear. Also, I think that the base/clear is what I want for the Tor-red but if not, help me on that. Thanks.

BTW, I got some solvent free w&g remover from SPI that I will try next time. I had used a solvent based Duplicolor that time. Again, thanks.
