My local paint supplier quit selling Valspar products, so I had to go back to using PPG, but its been awhile. Can K36 be out in the rain? I radiused the rear quarters on my daily Ranchero, I have them in K36 right now, but they still need to be blocked out. Can I drive it this way, (in Oregon), or do I have to spray them with DP or something first?
Hey K36 should be OK to be in the rain because it has a hardner (K201) As long as it hasn't been sanded, because sometimes if its open it will start to crack(over a long period of time) If it has been sanded I would recomend putting DP or something over it. Hope this helps Later Darryl
Thanks- So basically, if the material is catalyzed, its safe in the weather? is that a pretty safe rule of thumb? I was planning on sanding it before I drive it, but if I sand through it, I'll recoat it.
I would say that's a fairly accurate statement. Also, as a general rule, the glossier it is the more weather resistent. I wouldn't worry about even sanding it (the K36) if you're only talking about a short period of time (say...a few weeks max?). But you know how that scenerio goes: "Ill get this painted next week." - two years later you're thinking "Im going to have to re-prime this...". In either event just make sure it's good & dried out before applying any further coats (of anything). ~ Paul aka "Tha Driver" America - made in China! :-(
Consider it a blessing in disguise if you don't get to it for a bit. I fuckin hate K36...it shrinks too much. They now have a 3000 series primer that has high build, quick drying time, almost zero shrinkage. We just used some (1st time for me) on Mon of last week on some epoxy base fiberglass panels. I was pretty impressed with it. Even on those "sponges" they gave us to finish the shrinkage was almost total zero. As for the topic, i agree that if it's got some gloss to it you'll be fine. I can't speak about the UV resistance, something that DP has very little of.
Nobody said they were. The guy just wanted to know if it was alright to leave it for a little while. BTW I hate K36 too. I use Sikkens high-build primer, it's the best but it's also high-dollar. ~ Paul aka "Tha Driver" You just shot an unarmed man! "Well, he should have armed himself."
Define "a little while". It's pretty wet in Oregon, I wouldn't run my car in primer, without top coating it with paint. Rattle can clear laquer is easy to sand off and gives you pretty good protection. Maybe I'm paranoid. Or maybe I've just seen too many cars rust under primer. You want to risk it, go for it.
http://www.ppg.com/cr-refinish/phase1/frmFindProduct.asp More info here on the ppg 3000. It's the DPS line and we used DPS3055. There's a tech sheet here also and it takes Adobe Acrobat to read it. It dries fast, shrinks almost not at all, sands real easy with whatever you want wet or dry. Comes in white grey, and dark grey. Yeah, I liked it a bunch. K-36 should go the way of Kondar. Kondar was really garbage.
I work at a hot rod shop in so cal. i wouldnt recomend leaving any primer in the rain its like a sponge after paint it will come back to huant you
Doesn't matter now...The blocking went better than I figured, I guess I'm a better bodyman than I thought!(thats a scary thought...) So I will be ready to spray a good sealer on it by about Tuesday. Thanks for the advice, as always...
