Hey Herb…lost your phone #. If you don’t want to broad cast it you can e-mail me @ . Found some info on glossing. Tell me if this might have been a problem. My best gues is that the temp in my garage is approx. 85 degrees maybe hotter. I was kicken a pint or so with 18 cc of catalyst and it still was takin 15 mininutes or so to gel ( at least it seemed about that long). Do you think it is more likly that the wax solution in the resin separated or more liklyt that the chem reaction was too hot and kept the wax from rising to the surface. The sheen you see as your glosscoat is kicking seemed minimal. Sanding it off yielded a pitty grainy sand dust but there wasn’t alot of the gummy buildup on the sandpaper. This one is boiling down to experimenting on a beater board befor i try it again on my good one. signed, Bewildered JC
JC, There are 3 major NO-NOs in coating,besides the scads of other pitfalls that can occur. 1)= AIR FLOW , you want to achive “ZERO” air flow during hot/gloss coat appication,and set-up time. 2)= MOISTURE, If you have and moisture in ,containers,fresh paint jobs,on the blank,etc,etc,etc. 3)= OVERHEATING THE BATCH,Too much heat + too much catalyst = bad nightmare. 3a)overheating…if the coat is browned like rootbeer,and the surface is like a plowed field it’s probably overheateD. What happens is the gloss is old ,and lacks enough styrene to make the more congelled wax rise to the surface.,and because the batch goes off so fast the wax get suspended in the the coat somewhere(usually the bottom of the coat,causing delam)…I wouldnot have mixed that amount of cat. to the ratio you have given me…what I WOULD HAVE MIXED IN 85 DEGREE WITH A PINT probably 8-12cc of CAT. and would have(knowing the gloss was old)added some styrene or agent or both.The plowed field look comes from your brush stroke,the coat goes off so fast that it takes on the signature of the brush strokes as the resin heats up drastically(it shrinks and/or cracks).Herb. 2a)moisture…leaves wetspots or coat will not go off ,your surface remains flat ,but usually very tacky if it goes off at all. 1a)air flow…leaves ripples ,like large “orange peel” like surface(lumpy).Herb

I’m sure it’s not that. I’m going with more wax solution and less catalyst(don’t keep styrene aroun…too dangerous w/ kids and animals that like to get into things) and try to gloss in the cool of the morning with the door closed to keep glossing gnats and mosquitos and love bugs into the board. will let you know how it works. Its funny because the board i did a few days befor came out just fine. Go figure! JC
I keep waiting for one of you experienced builders to spray hot coat Suncure. Spraying makes the coat consistent throughout. You have to age the coat for about 15 minutes to clear up the froth before exposing the Suncure.

Hey Herb, Those frog eyes may be from moisture in your air line/compressor.
Hey Herb, Those frog eyes may be from moisture in your air > line/compressor…I have a water trap,but you maybe right! I NEED TO BLOW OUT MY 50’ AIR HOSE BEFORE HAND!!!Thanks.Herb.
Scott nailed it! Except for frogeyes, I’m glad it worked. …one more reason for shops to use Suncure.
I have the same water-in-the-hose problem. I wonder if placing the trap at the sprayer end of the hose would work? That would make unplugging the gun trickier, but it might be worth it.

p.s. this gives me another look at a new dimention in color coats???
p.s.>>> this gives me another look at a new dimention in color coats??? Herb, Noodle, You can get cheap disposable in-line water filters at a NAPA Auto Parts. They are plastic and you screw them right on to the spray gun and reinstall the air fitting to the filter. They work great! Last thing the air sees before your gun is a filter! Use a gravity feed gun(40 bucks Harbor Freight) because they spray thick stuff better than a siphon feed and are easy to clean. Scott W.
Herb, I don’t know where your water trap is mounted in your system, but this may help all you guys. The water trap needs to be remotely mounted away from the compressor as high as possible. (a minimum height would be above the top of the compressor tank) Run a hose from compressor to trap using the compressors full PSI. Intall the regulator after the trap and then the plastic filter Scott mentions at the spray gun. Over six gallons of primer and six gallons of lacquer on my El Cam in all different types of weather over a year period (even rainy days/nights) and never one drop of water out of the gun. Aloha, OL
Thanks Scott and OL! Yeah, I tried a trap after the regulator. It didn’t work. A high-mounted trap before the regulator, and a gun filter sound great. I like the gravity feed gun plan. It could spray resin with less styrene… less froth, shorter evaporation time. Herb, I get your drift. That type of color looks great, relies on consistent coat thickness, and lets light in… Custom fit! Next board, I’m all over this stuff!

Uh…eeeer-this is a lot of jacking around when a brush works just fine fellows
yea,but it’s fun to play!Herb.
