After wire brush, degreasing, and acid etching......preparing for the POR-15 paint Image Unavailable, Please Login
Skipp, I would recommend you lightly coat any exposed skin, face and arms, with Vaseline or similar. POR-15 sets up quickly with the presence of humidity, sweat, and turns rock hard. I had big black drip dots all over my face and arms after treating my F-150 on a 2 post lift last year. I had to sand it, and it took over a week to wear off. Use rubber gloves, a particulate face mask, an old ball cap backwards, an old long sleeve shirt, and safety glasses to minimize skin exposure. I am on my 2nd gallon of POR-15 in the last 5 days @ $145/gal. Quarts cost more overall, but you only need 1 for this job most likely. The semi gloss black is probably the best for your job. Here's a good tip... I also don't open the can lid. Instead I use 2 rubber gasketed sheet metal screws in the top of the lid at 180 apart. Take them out, pour as needed, and reseal. If you leave ANY residue in the can lid sealing grooves, the top will be permanently sealed. If you open the lid, the grooves must be PERFECTLY clean when you reseal the lid. Any air gap will also ensure the whole can is rock hard by morning. POR-15 loves air. I've also found the disposable foam brushes work the best by far. Good luck!
Thanks Jon. You speak the truth. I've done this once before on my old Alfa GTV6. Went with small cans this time. Image Unavailable, Please Login
I used por-15 on my 308 chassis a few years ago and it still looks fantastic. It's amazing stuff... harder than powder coat. However it is not user friendly. I found it impossible to seal and then reuses he can Next time I need to use some I will definitely go with the small pots shown above.
Making progress. Arrived a bit beat up, but I'll pound the dents and get powder coated. Making Templets now. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Templet completed and holes located and drilled into new undertray. Powder coating and installing next week. Don't let this happen to you ! Make sure your tray is secure. What a pain in the A$$. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Look at it as a positive. You took care of some rust. In the future, don't drive a car at high speed without giving it a good looking over. Be thankful it was just a piece of undertray which fell off.
Powder coating seems a little overkill to me. You could use zinc chromate primer and Rustoleum satin black and it would last for several lifetimes unless you drive on the beach.
Here's finding the holes. Used a hole punch and then tested all rivets. Image Unavailable, Please Login
While I was at it, I did the grind and paint treatment to the majority of the lower frame. It was covered by old rubberized coating, which I sanded off and retreated. Stage two will be the areas around the suspension while I'm rebuilding those components. Image Unavailable, Please Login Image Unavailable, Please Login
I dropped the front piece at 220 kph (I think I ran over a bit of tyre rubber on the road in the twilight). It was exciting for a few moments to be sure! It was left dangling by a couple of rivets making a god aweful sound until we came to a halt. We got it off and lobbed it over the armco and continued North.
It truly does sound "exciting" when that happens. Very mechanical sounding. Especially when it's coming from the rear !
