pinstriping

[fastvetteC4]

anyone had trouble w/ silver urethane striping paint [house of colors] .i applied silver and red pinstriping over tinted urethane with the silver crinkling urethane under neith.red color came out fine.let paints dry for two weeks @75 degrees .tried to thin silver but still got a reaction. it is acting like its not cured enough. really harshed a triple candy intertwining flame job. does that silver have that much penetrating strength?how do i keep this from happening with that color again?

When you stripped with the silver was the urethane broken through? was the graphic edge exposed in othger words. the stripping enamels will reactivate the HOK base coats under the urethane giving it that effect.

i first shot the flames on w/ 3 coats bc-02 , 2 coats tinted clear. my thickness was so much that the striping tool or striping paint would not fill it in leaving a definate edge.so i wet sanded and applied 2 coats clear over entire car. then wet sanded again to flush out the flames more ,then continued to stripe.but when the silver reacted it typicly originated at the flame edge.after sanding the second time there could have been an open break at the flame edge.is this the correct process for trying to flush out the flames when your millage gets to that point.i cant think of to many other ways to creat the candy effect with less coats or less millage.most of the reaction of the silver went away after doing subsequent applications but it still took about 10 coats of 2021 to completly flush the flames w/o breaking through at the pinstriping.this is my second paint job but i love doing it, so i am trying to learn at an acelerated pace to create paint jobs of this caliber.

A way to get a candy effect with out the millage is to use the Kandy Base coats or mix your own using KK and SG100 . by the way you described your paint job you had a pretty high graphic edge. when i do graphic work to burry the edges i spray 10 - 15 coats of clear total,depending on the millage, wetsanding every 4 - 5 coats. it is time consuming but it is the price you pay for quality work and no edges. hope this helps

I noticed you used 2021,great stuff.I can't help with the HOK stuff but 2 coats of 2021 is just enough for the protective millage with a fine scuff-n-buff.Even doing a normal 2tone in basecoat and trying to lose the edge cuts it too thin IMO.It sounds like when you sanded out the edge the clear was too thin on the line.Even if you don't break through if the clear is thin enough that even reclearing it can wrinkle the edge.So far I've had good luck with the rule of every 1.5 coats of base gets a coat of clearto lose the edge,but if oyu think you hosed eack coat on go an extra on the clear.This is on the conservitive side and EZ's idea is a sure bet but I'm anal about millage.Just remember to add a little to the flash time after 2 coats to avoid popping-+5 minutes is usually cool unless it's really cool out.Remember to let it sit a little longer before sanding too to avoid serious shrinking later on.
