some places do carry it, but I found it just as easy to order and it is about the same price either way...get a mix pack if you want to try a little of each....and a little goes a LONG way. only 2 days and it was at my door. I bought one of their mix packs. I did the por-15 for 2 coats on the frame in my engine bay and then did the chassis coat for the UV protection..and honestly, I should have done 2 coats of POR and quit. the last chassis coat did not look as nice...maybe because it was from build up with 2 coats under it. I figured that maybe I needed the UV protection from the chassis coat with car shows in parking lots, so I put it on. did not totally screw it up, but looked better with just the POR 15 on it. I would try a small segement of each on an undersided surface and see what you think. by a bunch of cheap hair brushes....don't use
synthetic....made that mistake as well. and then toss them, do not even try to clean them. buy rubber or plastic gloves to keep this off your hands,, hell to clean off. I suggest getting more smaller containers and not the larger ones....and poor some into a container to paint from....immediately put the rest in a baby food jar or similar and make sure you put a piece or wax paper or similar between the lid and the jar. you will never get the lid off once it seal on if you don't have some type of barrier. I think I used a side of a zip lock bag. I also used the zip lock bag on one of the small cans and just put it between the lid and the can and hammered it back on tight...that worked. Also, do not do the prep solvents in the garage, cause they have to be hosed off and that is a pain. I did all the prep steps and caused a huge mess in the garage. when you start, have the car on the wheels so when it is time, you can roll it outside to hose the chemicals off and let it dry...then roll it back into the garage and paint. So, small cans, not the large....rubber gloves....disposable brushes (get a few different sizes) and know that the prep has to be thouroghly rinsed off. Good luck
