Hey Nick, it isnt as big of a thing with waterborne. There should be a hardener for your basecoat though. We have one for Autowave over here. I mainly use it for underhood applications.

When using sherwin Ultra 7000 line, you dont have to use hardner in the base. It uses a intagrated stablizer. Every step through is flexed, I pesonaly dont like hardner in the base due to the fact of how much slower it makes it dry.

ya know i really like the way that integrated stabilizer make our base handle even the i dont go nuts over the price its well worth the money though

I seem to struggle with the new stabilizers. First off, if I have to nib any dirt out of the base before clear it takes forever to flash. Second, I think the integrated skims over on the surface leaving the bottom wet wich leads to die back and slower flash time. Third, I get more mottle with it. I know that goes against what everyone else says about it. I just sprayed a gold Honda with it, it mottled like crazy, went back and remixed with the old stuff and had good luck. Sounds crazy but the old stuff works better for me. Only prob...My rep wont sell it to us due to our wananty.

no fooling it seem ta work the opposite for me i use trs4 for every thing have been since its introduction but im running the fluid in about 2 full turns on my rp 1.3 so i might be putting less on each coat

this is how i base with my rp your using the solvent right??

Yep, using solvent. Im using PN. RFH75 and sometimes 85. (Med and slow). I use a sata 3000 HVLP. I have never tried an RP for base as I dont have one. I set my gun at about 2-2.5 turns out fluid and about 20-25 psi. I have also found that if I use a very slow stabilizer such as tropical(90-110 deg) I get better results. I am spraying in a nice spraybake that has very little air flow (bad grate design). I think that has something to do with my integrated stabilizers drying too slow and giving me fits with die back. As far as why I get more mottle with them? Not sure.

Underpaid Painter,,,,If you cut back a little on your stablizer and add reducer, It will speed up your flash time. It helps a lot. I know how slow S/W base is.

Thanks for the tip ODG! How much reducer do you sub for the RFH?
