Real-time help - paint

[Fast Eddy]

I am painting my half doors with omni single-stage. I'm getting something like krinkle-finish out of my gun. It's a harbor freight quality hvlp deal.

WTF?

crinkles sounds like you have something uncompaitible under it...like rustoleum primer thats not fully cured or???

Did you thin your paint w/ anything?

 

[poopboy]

Sounds like oil or something else under the paint. Did you wipe it down with something before spaying?

You have a contaminant on the surface. You have to removed the stuff you sprayed first, sand down the surface again and use grease and oil remover like dx330 from ppg. I'm assuming you sprayed it with ppg's omni 175 epoxy primer first or it's equivalent?

Ditto - Contaminant - or improper primer sealer. Use the acid etching sealer mentioned above - preferably the PPG line - I've been spraying that this week in the flat black version and it just goes on so sweet.

Alternatively, what mixture is required and what reducer did you use?

I started to use the PPG Omni line almost a dozen years ago, didn't like the color match or the quality on the test pieces I did - dumped the stuff and paid the extra for PPG Delstar (which they don't make anymore). Definitely a big savings - but I just pulled a 7 year old gallon of the Delstar out, and mixed it with Omni reducer and the Delstar hardener - and it came out pretty good for old paint.

Ruh-roh. That's the fact, jack.

My new story is that I was going for a textured look. It turned out just like I wanted.

The mixture was supposed to be 4:1:1 but I found an extra .3-.4 of reducer made it spray better. Lesson learned on the primer. One side has been in primer for two years. I just copied the 2nd one with the same primer (Rustoleum Automotive Primer). I was in a hurry, so I painted only a few hours after the last primer coat.

The bib turned out perfect. F'n spray can. :sigh:

The little rectangular piece bolts to a receiver insert. It's a step.

Ya man I thought I knew that look...rustoleum off gasses or something. I have had the same thing happen to me when I rushed shooting some paint over it.
