Lacquer Painters, Need Help!
A fellow forum member is in the process of painting his '70 convertible with Laguna Gray lacquer and running into heat related problems. The paint on the rear deck is streaking.
Does anyone have or know where he can get some drying retarder?
Please let me know if you do.
BTW, his forum id is $tingray.

Not sure what you mean by streaking, metallic not even or sheen not consistant, but here is the retarder. Any Dupont jobber should have it.
Most other manufacturers carry their own too.
DuPont™ 3979S™ Acrylic Lacquer Retarder
In a pinch some hardware stores carry it for wood cabinet finishing, but it is not as good a quality as the auto stuff.
Here is Porter Paint's a beter quality than hardware stores.
Porter Lacquer Retarder #863. They are now owned by PPG and have stores in most metro areas.
Sherwin Williams Automotive has it as Universal Retarder R7-K6251

Thanks noonie.
They way he described it to me is it looks like there are stripes on the rear deck. I am assuming they are the width of the spray pattern.

He did also mention the metallic is not spread evenly.

Retarder is generally used for the sheen, to prevent orange peel, dry spray, and moisture entrapment from too much humidity.
Sound more like he has application, mixing, technique problems. Lots of practice for heavy metallics.
Retarder is strong, so be carefull about shrinkage etc.

Retarder might help. But streaking can also be addressed with both increased reduction (more thinner) and more fluid/less air at the tip so you achieve a wetter coat. A slower gun arc might help as well. I assume he is using the slowest thinner available from whoever is supplying the paint? Be careful... weather hot enough to interfere with paint flow often contains enough humidity to make "blush" a real possibility if you play with wetness/drying speed. It was 96 degrees here in Savannah today with humidity over 80 percent... I wouldn't want to try a lacquer job here right now even in a great booth!

It was around 100 today but only about 48% humidity here in Wichita.

BTW, looks like we're stuck with low to mid 90s for the next week at least.

Yup... been like that all week, and probably next week as well. So far no thunderstorms right here to relieve the heat... probably in Brooklet tonight from the look/sound of things??? Hope so, we could all use the rain.

If your friend is paying someone to do this job, and we're having this conversation there's an experience gap that needs addressing. I know that lacquer is a "fading" paint medium, but I'm not a fossil yet and it was common in my youth. I council a "stop and regroup" session with the owner and painter if the issue has not been resolved "for a couple weeks now". $tingray... what's the "real deal" on the paint for your car????

I don't think patience is an issue. He spent about 2 months getting the mixture right to match a 1970 color sample he has.
I think it's more a problem that the painter, who is a very good friend of ours is not well and his hands shake a lot these days. If I remember correctly he is 71. But he does beautiful work. It just takes him longer these days.

At 71, something tells me he's got a lot of experience with this.
Should have no problems with the retarder, hope he used a real sealer over the primer. On a high metallic like a grey, the last coat can be thinned a little more, a little more distance with the gun and a lot more speed. Object is just to mist for the metalic uniformity.
Good luck.
