Krystal over resistant ?3/16
I've tried Krystal over resistant with better results than 2 coats of resistant. Has anyone else used clear over pigmented finish? How did it turn out? Any advise would be great.
We often put a clear coat over our pigmented cv. Adds depth and makes touchups easier.
Dan - what problems are you having with the Resistant? It may be possible to work out the problems and avoid the additional labor and materials of applying another coat.
Paul- just seams to get the odd fleck of contamination or just not as nice a finish. with the kystal it seams to finish off nicer.
I've been using MLC Resistant Pigmented top coating for long time now and have been having more and more mixed results with the finish quality. Regardless of my in shop temp and humidity I'm routinely adding a little Care Retarder C161. Starting this year I'll likely change more product to MLC Stealth Post-Cat. Suggest you try the C1621 Care Reducer along with the standard C16036 reducer.
Sounds like Richard is having the same problems.
I was faced with the same situation before. I tried a number of things to get the finish to work well including various thinners in various ratios as well as changes to the spray equipment and spray technique. In the end, I had to switch to a different product to get the results I wanted and was very happy with the results.
Maybe someone here has overcome the problems you're seeing and can offer some advice. If not, consider testing some other products. Anytime you add steps or additional products to your finishes you are cutting into your profits (unless you adjust your pricing).
Richard. I used the reducer and it helped and thinned it more. I usually only use the retarder when it extremely hot out.
I gave up on Resistant and switched over to Stealth. Took a while to figure out how to get it to work consistently.
Use a mixture of Reducer and Flow Enhancer #2. I usually make a 50oz mixture of the concoction, 20oz #2 and 30oz Reducer.
I'll mix up 20oz of Stealth and put 4oz of the mixture in it (20%). In the Kremlin I use 35psi liquid and 17psi air (trigger pulled).
As for putting Krystal over Resistant, why not. Only thing is Krystal will impart a very slight green hue to a white.
As Leo said, there can be a slight color change on light colors esp. I found out the hard way. If you're matching something closely, do some samples to check.
if we intend to clear over the pigmented, we do so in the sample submittal stage. That way the customer has reviewed and signed off on the final appearance.
But as both above posters have mentioned, clear definitely changes the color and look.
A typical scenario where i find it beneficial to topcoat over pigmented is on the high gloss. You get a much more brilliant gloss when you apply a clear over the pigmented.
Ya know I just asked my MLC rep that the other day , because we are spraying some really dark resistant , but my rep said Krystal over resistant would do no good . Though we have done it with some of there pre-cats.
I'm sure Leo's reduction flows out really well, but I always experiment in how fast I can get it to cure with an acceptable appearance, and with Stealth I am consistently reducing 20% with acetone and getting great results.
I struggled with Resistant years ago, especially dark colors. Orange peal city. I even gave up on black all together opting for an extra coat of Clawlock with a clear coat.
