right on im going to just try a test panel and see how it works, trying to color match some patina on a set of truck bed wheel tubs from 1963You would start at about 25% to the clear test and add from there, depending on your desired gloss level. Activate only the clear, not the flattener (go to 3 on the mixing cup,
Activate and then add 25 or so %of just the clear)
Now the bad news is you can override the flattener by loading coats with no flash, time, and I have never heard of anyone using the speed clear with the flattener. Does it work? I have no clue, but when I get back Friday, I will test and see.
Yea i wasnt 100% on the mix i did, if that was right or not, i have the TDs on the su4985 flattening agent and it confuses the heck out of me. ill try that ratio and see what happensProper procedure would be to mix the Speed Clear 3:1, then add +-50% flattener to the activated product. It seems likely that your clear is overactivated.
The su4985 is NOT consistent. Our shop uses PPG. We switched to the premixed D8115 D8117. That being said, Flat clears are sprayed different. PPG’s (even using su4985) you spray light coats and must let it flash off between coats until it is completely flat. Then spray your next coat. The reason the data sheets are confusing is because one sheet is mixed by weight and the other sheet is by volume. If you notice they list a whole bunch of different PPG clears. And if you also notice, the ratios are all over the place. The ONLY way you are going to get it is experimenting.Yea i wasnt 100% on the mix i did, if that was right or not, i have the TDs on the su4985 flattening agent and it confuses the heck out of me. ill try that ratio and see what happens

Can Utech 890 be purchased in Southern California?Jim C turned me on to Utech 890, which is a good substitute for the disco'ed SPI flattener. Read the TDS and it gives a good guideline for gloss levels and amount of the product to use. Works well with Universal and Production. Probably the other 2 SPI clears as well, I just haven't used it in them.
I have no idea. Check with a Akzo Nobel distributor in your area.Can Utech 890 be purchased in Southern California?
