2nd coat of epoxy?
 

Did not get complete coverage on a few plugs, missed a few spots, and I want to apply another coat. How long do you wait till you reapply another coat? I used mirror coat and I put the first coat on yesterday, Wed., at 3 pm. It says if you wait 72 hours than you need to scuff it so I want to know what is the soonest you can wait because I need to be dry by Sat. morning. Thanks Paul

Take my advice with caution, but I think if you warm it will cure much faster. I think I read somewhere, probably the system three faq site, that you can halve the curing time for each 16 degrees you raise the temp. I've recoated their Clear Coat product after 48 hours without incident. I'd try a heat lamp and spinner overnight, then recoat tomorrow, and hope for the best.

Paul, not that I am an expert but..... I would do what I do and use a light coat of 2ton/two hour epoxy by devcon. Do it tonight before you go beddy bye and voila hard as rocks by dawn. Just did it this week twice as a matter of fact.

Haven't tried that stuff but in my epoxy world apply the next coat after the 1st is tack free and b4 the 72 hrs.

Now to further confuse the issue I have put the second coat on while the 1st is tacky but not sagging with no adverse effect. You just dont want the tacky so tacky that it pulls brush hairs. :tm:

Brush hairs are the nemesis of plug builders! I always seem to miss them and see them clearly after the plug has dried. I hate those things!

When I've had to recoat, I've sanded with a maroon scuff pad, wiped with isopropyl alcohol (previously acetone but this strips the bare spots) and then applied the epoxy with my finger (in a powder free glove). I seem to get a smoother, thinner result with less bubbles. Just don't try and touch it up latter once the epoxy starts to grab. I'm using the system three clear coat, however, which is a very thin product to start.

You just missed a few spots right .. They are not tacky ? are they .? I know this is very stressful .. Are you being to picky ? I know how you machinist are with perfection.. I have had problems putting a better mix (hotter coat) over a sticky coat and got a shriveled effect,, sux..

Paul, If you are only talking a couple of small spots don't sweat it. Leave them be. If the area is like 3/8" then recoat.

Thanks guys for the fast response. Screw it they are good enough, I can't believe I said that. They came out great except for a few spots and instead of ruining it I will let it be. P.

I also have another question. I seem to be getting too many bubbles in my mixing process, I know Chris humor me. Would pouring the epoxy out onto a larger surface other than the cup I mix it in make the bubbles pop easier being that the mix is not thick and they can rise if the mix is only say .0625 thick.:whackin: In the cup they don't seem to rise up to pop. :conf: Paul

Paul,, don't worry about bubbles.. I think of Larry Welk when mixing mine.. where do they go, flying out of the cup?.. Don't worry about that either... :D

Bubbles come.. bubbles go, warm mix, clean, clipped brush, all is good. Like the sensei said.. wax on, wax off.

You can blow in the cup ... wait .. blow some more if you feel like it wait ,, most should go away ... carbon dioxide kills bubbles... makes you dizzy though and you may pass out .. see u at plugfest .. Me and the pigmy poney over by the dental floss bush ..

Thanks. See you on Sat. I'll be the one "with my tweezers gleaming in the moon lighty light"

I couldn't see myself in Montana soon, no tide.

but we could all hang out at Joes' Garage though.

I don't believe I just read this!:bc: There must be some kind of cosmic misalignment somwhere in the universe!

:rotfl: I was thinking the same thing

Now Paul get back to work making my cutter:lasso:

Hey St. Alphonso, PNG, were you delighted as it stiffened and ripped right thru your sock.

still picky enough to write .0625 rather than 1/16.......and you just had to add the .0005 :smash:


I blow into the cup just before i start applying (e-tex) to pop the big ones, then get the rest once they are on the plug. i coat one, then pop the bubbles. the longer you wait the harder it is to pop 'em. keep blowing untill you get headspin. :spin:

slip (i think) posted in another thread awhile back that if you mix the two parts slowly, you get less bubbles.

and use something round like a dowel to mix it, not a flat popsicle stick
you get less bubbles with a round stirrer.

:bshake: Saint Alfonzo would be proud of me

Instead of using your breath use a propane torch set to low and at a bit of a distance away and use sweeping motion.Works great and no dizziness.

hit the bottom of the bristles with a few drops of zap or head cement.

For my missed spots, I touch up with Sally Hanson Hard as Nails clear nail polish.

All great ideas guys thanks. Hey Chris "your poodle bites your poodle chews it" P.

whew!!! I thought I was the only one walking up ad down the nailpolish aisle at WalMart!! Great stuff in a pinch. Every once in a while I get a little spot that's a bit tacky, the clear nailpolish does the trick.

Well I'll jump in on this....

I'm bringing Peaches En Regalia for chowfest :devil2:

My method exactly and you don't wind up epoxy on your lips.:eek5:
