Default Bill Hirsch Black Miracle paint.

I painted my new floor pans with the miracle paint. I sandblasted the panels, then used wax and grease remover. After it was dry, I painted the panels. To my surprise I kept getting air bubbles. I brushed it on, I tried a roller and still got bubbles. What am I doing wrong? The room was warm and so was the paint. Please let me know your experiences.

It was probably the wax and grease remover. Was it PPG?

It's been my experience and I've read you should use wax and grease remover BEFORE sanding or blasting. The thinking is that if there is any wax or grease the mechanical paint removal can drive traces of these products into the scratched metal. This is especially true of silicone based waxes (which I doubt would be on your floorpans).

A solvent-based wax and grease remover could do this too if it were not TOTALLY dry before painting, as the evaporation of the solvent could form bubbles.

Of course, don't count out the fact the brushing/rolling could be introducing air and the viscosity of the paint is trapping them as it dries.

By this question, my first thought was that you thought PPG might be at fault. But maybe you were just asking if he used the PPG as being the more quality product?

you need to use thinner on the parts after sand blasting them. to get the metal clean.

I've seen people have problems with residue using PPG. I used it once at a friends place and had no problem but did not like it's characteristics being used to R-M 900.

In reality I use R-M 900 more as a specialty solvent for other things and rarely use wax and grease remover for it's intended purpose as I just keep things clean.

Thanks for the information. The floor pans were new. I lightly sandblasted them. There was no oil on them. The first time I used the Miracle paint I put it on the bare metal with a brush. I got air bubbles and I thought it was to thick. I only did the bottom side so if I had bubbles it would not show, Next I took another small panel and tried it with grease and wax remover. I still have bubbles. this Miracle paint is like POR15 Please let me know if any of you have used the Miracle paint and what were your experiences. I also called Bill Hirsch tech people and they have never experienced this before.
, this product is not PPG. It is like POR15

Did you shake the can of paint? Many times the can will say to stir but not shake, as shaking introduces a lot of air bubbles, especially with something thick like POR 15.

I haven't used Miracle paint but have used POR 15 and they are similiar products. The instructions with POR 15 says to use NO solvents before application. If the solvent had been used before sand blasting you probably would have had no problems because sand blasting would have removed the solvent. Instructions must be followed to the letter or you can expect failure in one way or another.

I have a can of Bill's Miracle paint here, states you should shake, stir or mix paint well first. ALSO, recoat time is 4-6 HOURS after the first coat loses it's tackiness. Is there a chance you recoated it too soon with a roller and it's lifting?

I think sand blasters are sometimes held to too high a standard which can't be met when many jobs before yours had greasy crumbs which contaminated the medium. Tough to really clean the rough, fresh blasted metal. Good Luck: Fred A

I use carb cleaner to remove all signs of grease before I paint.
