I am painting my bronco metallic silver with a blue pearl in the clear. my first time spraying. I sprayed the jams this weekend and put the blue pearl in the clear. The guys at the auto body store stressed to me not to use too much pearl or it would be overbearing. So I was kind of nervous I would use to much. I added a bit to the clear and in the mixing cup I could see it, looked cool in the cup like bioluminescent or something like that. Sprayed the jams and I can not see the pearl. shined it with a fluorescent light and could not tell. So I am going to be spraying the truck this weekend and clearing it. How do you know how much pearl to put into it. I would like it to be noticeable but not too much that it takes over the metallic paint. also would straining it filter out the pearl powder?
thanks

The ONLY was to tell how much pearl to use in the clear is to do some spray out test panels. Get a piece of tin (old fender, hood etc) at least a foot long and spray it the silver color you plan to use. Get out some paper and tape and make 4 equal section of the silver by taping and papering off those sections. Number them 1 through 4. cover 2, 3 and 4 sections with a piece of paper. Next MEASURE how much pearl you think you need into a measured amount of clear. Spray the first section with one coat of the pearl/clear mix then cover that section. Uncover panel section 2 while leaving 1, 3 and 4 covered and spray two coats of pearl/clear on panel 2. then cover two and uncover 3, paint three coats on three and four coats on panel section four. Pull the tape separating the separate sections and spray a coat of straight clear over all four panel. Let that setup decent then take it out into the sunlight. Pick which panel that YOU like the most. The odds are that one coat will be almost invisible and four coats will turn the silver paint a blueish color. So the odds are you'll pick between two or three coats of pearl/clear mix.


One other thing. You would be much better served if you used an INTERCOAT CLEAR as a vehicle for the pearl. (mix the pearl into the intercoat clear instead of full thickness urethane topcoat clear). An intercoat clear is the same chemical makeup as plain old basecoat except without the color pigments. Its much easier to work with and is relatively inexpensive compared to topcoat urethane clear, less buildup etc etc The PPG intercoat clear numbers are DBU-500 or DBC-500 (depending on which one you like spraying, I like DBU over DBC).

ok that makes sense. I was told to spray only one coat of pearl in the clear and then 2 or 3 coats of just plain clear. I was saying to myself how the F am I going to get it right the first time around.

well i already bought a gallon of the clear. would it be ok to get maybe a quart of the intercoat for the pearl and then spray the plane urethane clear over that? Also what do you feel is the optimum coats of clear?

The intercoat clear does not take the place of the regular urethane clear in the finished project. It goes like this - spray the silver basecoat, then the intercoat clear with the pearl mixed in. Finally two to three coats of urethane topcoat clear. (point being you'll still need the gallon of urethane clear you already bought).

I personally would spray two coats of urethane topcoat clear on your project but them I have a lot of experience painting so my second coat of clear would go on pretty smooth (no serious wetsanding to get a decent finished shine). If you are less experienced than its probably a good idea to spray on three coats of urethane topcoat clear which will leave you a little room for color sanding before you use the rubbing compound.

A quart of intercoat clear would probably not do your truck, pick up a couple quarts (that should be enough as long as you're not doing the inside of the box etc)

thanks for the advice. this is my first time spraying so i will go with 3 coats!
I will just pick up a gallon. I plan to paint my waverunner after this and will also put a pearl in it so it will get used.

of an intercoat clear. dumping or measuring dry pearls into a urethane clear will not work...at least for me. the pearls never fully disperse in the clear & will give you blotchiness big time. before the advent of intercoat clears, i'd put my pearls in a mixing clear binder & shoot a coat or two & then a couple good coats of urethane clear. be sure you record part #'s & the grams used in case you have to re-do the job.

I use liquid pearls that I mix with clear for spraying. I've never had a problem.

Maybe I'm just seeing things, but in the picture of the underside of your hood, it looks like you have tiger-striping of the metallics in the silver. You might want to practice your spraying technique and gun adjustment on some test panels before you do the whole truck. You will be very disapointed in the result if you get tiger-stripes. I don't have the experience that many of the guys here at the forum have, so I'll leave it up to them to offer the advice on how to avoid tiger stripes.

thanks I dont think that is tiger stripping. The underside of the hood was pretty beat up and I did not really spend much time repairing it as I plan to do a cowl hood eventually. this lines are from the rust bullet I used a roller to apply to prevent and further rust. That crap is rock hard and a pain in the butt to sand smooth so i just scuffed up the underside of the hood and sprayed it. I was not really concerned about looks of the underside of the hood.

that might go well as an archived lesson on " what happens when you rush a job" ...not bein critical...was just sayin, while I was admiring the silver you did on the exterior, Nice !

done! had to get to work early so the sun was just coming up. will get some pics with the sun shining on it this weekend. kind of pissed can not really see the pearl. I used every last drop of the pearl and sprayed almost an entire gallon of intercoat with the pearl, 3 coats and still not really visible. i think the metallic in the silver kind of out shines the pearl maybe.

looks good. Pearl reallyneeds sunlight to show up well. Id guess this is even more so true over a metalic color.

Pearl over silver metallic is a loosing proposition. The metallic breaks up the light so you can barely see the pearl. You would be better off spraying the surface a solid gray first then coating it with pearl because you would get a lot more of the pearlescent effect. Also when spraying an experimental pearl effect it's usually advisable to shoot a test panel first so that you can see what the outcome will be before you jump in.

i did shoot a test panel...i used the advice above about the 4 different coats. i thought it showed up on the panel, but i was cracked out on paint fumes so I guess I was halucinating, i guess i should have invested in the hobby air instead of the $150 i spend on the intercoat!
