Nancy, last year we pulled the engine out of my Volvo 1800 to swap the automatic transmission out for a manual.
While it was out, I decided to paint the engine using POR-15's rust preventive paint and then their engine enamel.
I began by scraping years of gunk off the engine and transmission with a putty knife. This removed caked on greasy dirt and some loose paint. Next, I used a toothbrush and Marine Clean (diluted 50%) and scrubbed away at both pieces to removed the rest of the oil and grease. I really took my time with this step because I wanted to make sure everything was CLEAN. Once done, I carefully rinsed the Marine Clean off with water.
Next up, I applied Metal Ready. I kept everything wet for 15 minutes as the instructions required. I used a spray bottle and just kept misting the pieces when they appeared to be drying out. After 15 minutes, I gave everything a very good rinse with more water in another spray bottle, then dried everything with some paper towels and let both pieces sit overnight to really dry out.
Next day I applied a coat of the rust preventive paint. I had no trouble with bubbling as one of the previous posts mentioned. In fact, I brushed it on and was pleasantly surprised at how well it leveled itself to a nice finish.
The day after that I applied my first coat of engine enamel. It took a couple coats of the enamel to cover the black POR-15 I had used as a base coat, but the results were absolutely wonderful and the engine still looks fantastic today. No signs of bubbling, cracking, peeling, etc.
In fact, right now I'm in the process of doing the same thing with the new transmission and differential for my Spitfire. /bcforum/images/%%GRAEMLIN_URL%%/yesnod.gif
I don't know why others have had problems with the product but I, for one, am a very satisfied customer!!!
