I spayed everything down with Turtlewax bug and tar remover. When I went to apply the base coat it’s like spraying water on oil. I’ll try and attach a pic.
The primer I used is UPOL UP2251 high build primer with their recommended hardener UP2327.
The base coat is High Teck HFP250 Ebony black with Grow Automotive 1380 Urethane Reducer(slow).

It appears to me that the primer is contaminated. Is there anything that will remove the contamination? Or do I have to sand all the primer off and then start over?

I appreciate any suggestions, advice , or experience.


:clap: :rotfl: :goodjob:

I choked on my beer when I read the post, then saw the Pic and about died :rotfl:

Every one has to learn, You like me it has to be the Hard way lol Thanks for sharing!!!!

Sand it all off, Clean bare metal thoroughly start over this time read all your Tech data sheets for all your products and follow their instructions!

So I finally got back to this project. After I posted last time I scrubbed everything with laundry detergent and rinsed it thoroughly. Then let it dry and wiped it down with actual wax and grease remover and had another go of it…….It was better, but I still had a bad spot in the first panel.
Then I went on vacation, a 4000 mile round trip on motorcycles for 10 days.
Then back to work and catching up on the home chores.

Which brings me to last weekend. So with my prior problems, I had used enough material that I would need more paint. And it was black. So I went to the paint store and changed my mind on color and went with blue.
I washed everything down again, this time with dawn dish liquid. I scrubbed everything with soap and a scotch Britt pad.Let it dry overnight, then on Saturday I got up, wiped everything down with wax and grease remover, and sprayed sealer on it since my primer was now wearing through from all the scrubbing. I then followed with color and lastly, clear.
I appreciate the input I was given. And you can see how I proceeded that I might be a slow learner,lol. But seriously, I think it came out ok. I have some cut and buffing to do, and a couple small runs. But it looks like it will work out. Here’s pics

The tank looks really nice. Sounds like it was a learning curve but don't feel too bad, I've learned the hard way in the last couple of years.

Wax and Grease removers their are two types One is water based they call it made from Alcohol the other is a chemical type based in Toluene I be leave? I am probably wrong!
Both remove Wax and grease from surfaces.

When applying that stuff spray it on heavy so contaminants are lifted off the surface and wipe with clean lint free towel in one direction only repeat till panel or part is wiped down.

NOW with that said Both of these cleaners are very different, Both used the same way.
BUT Both have very different drying times! I read and see a lot people say they go to applying paint immediately after wiping with W/G remover with no acknowledgment of allowing the W/G remover to fully flash off.

The Brand of W/G remover I use or am trying to use up both take an extremely long time to fully flash off I wait 24 hr for my chemical type and have had it been not long enough to wait! even though every thing looked good.

I have had many go a round's with this stuff actually causing paint problems because it wasn't fully flashed off. Anyone else seen this?
