I Hate Por-15!!!!
I recently received my awesome SR-III custom made tubular frame and it was recommended to use POR-15 on it. www.sriiimotorsports.com I diligently followed all directions and used their metal ready etching cleaner and began the application.
It was advised NOT to spray on since the vapors are extremely harmful and a pressurized mask with separate air source is required.
I carefully brushed this stuff on and did as recommended...applied a second coat when the first coat does not leave a fingerprint but the finger does not drag easily across the surface.
After putting on the second coat I noticed areas where there were drip s forming and sags. I attempted to "chase" every drip and sag but this stuff gels up quickly.
After not happy with the finish I sanded down certain areas and reapplied more POR-15. Again, the finish was not very good. I then snaded the entire frame for 5-hours in an attempt to remove all the imperfections. I tried to spray over this stuff with Rustoleum to make a smooth finish. Still after sanding for two days the finish is poor.
Now I want to remove this junk. Does anyone know if media blasting will remove it??? I tried regulat paint remover and it doesn't budge...:-(

WHY would you use POR15 on a brand new frame. POR15 is designed specifically to be used over rust on old parts, POR mean Paint Over Rust.
You shouldn't have runst on a brand new SR111 frame so no reason to use POR15.
i'd sandblast the entire frame to get that stuff off there, prime the frame than spray it with a good quality enamel paint and be done with it or get the frame powdercoated.

I have used POR-15 on many parts that would not fit in my oven for powdercoating and it does sag and leave wavy lines. I guess this is what they refer to as their "Self Leveling". Otherwise, POR-15 does work great as it is advertised.
I had my frame and other large parts sandblasted and powdercoated. The frame itself was only $625 for the entire process.
Good luck!

Since I did a little bit of reading on there site they offer two options. One is Prep and apply two coats DP90 epoxy black primer to frame.
The other is Powder Coating.

We sell por 15 and I have used it. There is no reason to use it on clean steel. Using an automotive primer and paint will prevent rust as well. We have customers come in thinking this stuff is magic. It has a purpose; painting over metal that has some surface rust. I used it on my truck frame and it worked fine. The regular por will get chalky when exposed to sunlight. This stuff is not really cheaper than auto paint and it won't have as much of a shine either.

Just because your coats sagged doesnt mean the paints bad. I did my entire chassis and underside (body) 5 years ago and it still looks brand new today.
Regular POR -Handles reflective light Ok, direct sunlight eventually it breaks down. THey make some topcoats that are UV safe and look awesome.
Didnt you post this in C4 also?

Rustoleum sells what they call their Professional Grade paint. It is available in either spray cans, quart or gallon size cans that you can either brush, roll on or put into a spray gun as well. I use the Gloss Black on mine, it is very durable and has held up really well so far. All I did was hit my frame with a wirewheel attachment on a drill and then painted right over it.

When I used to have my Z28 there was a thread on Nasty Z28.com about POR-15 vs Eastwood Rust Encapsulator and Eastwood won out big time. I used the Eastwood on an entire rear end housing for the Camaro and it came out fine. Just as mentioned, I simply brushed it on and was very happy with the results.

Keeping metal looking new
Has anyone use this product called RPM (Rust Prevention Magic) on cast iron parts to keep them from rusting? It is made by E.C.S. Automotive Concepts.
Thanks,
