How many clear coats can you use?

Hi everyone! I'm just got into hydro dipping. I sucessfully dipped my pistol slide after a 3 practice attemps with useless items :)

i have a question, after i dipped my item, i applied a clear coat to it after i let it dry for a hour,
that was 2 days ago. Is it OK to apply another clear coat now? idk if it will mess up the dip or something. thanks for the help !

    Is the clear in an aerosol?

    You should probably let the dip part dry more then a hour . And aerosols are spray cans

    oh! then yes i have the spray can activator. and i already put clear coat on it a few days ago, i think it looks good, i just wanted to know if i could add another clear coat even tho i already did it a few days ago, i just thought it would make the finish extra safe but idk if it will mess up the dip!
    i hope im not confusing lol. im pretty much just saying could i put another coat of clear coat on the finish (a few days after i dipped, and clear coated it) for extra protection?

    what could be the negative thing that could happen if i do decide to use another coat?

    You either need a chemical or mechanical bond between coats. To get the next coat of clear to bond chemically to the precious coat, it must be applied within the clear’s “recoat window” which can be as little as an hour to 8 hours. Maybe a bit more. You’re outside that window, so you will need to scuff or sand the previous coat of closet to get a profile (basically tiny scratches) in order for the next coat to bond mechanically.

    If you don’t do this, the next layer of clear will not bond and will not be durable. It will delaminate (flake off) of the previous layer easily.

    Just scuff it lightly with a red or green or grey Scotch Brite pad and then spray another coat...you will be fine...




    Remember I said LIGHTLY scuff it...not too hard or you will cut thru the previous coat of clear...and then you will have problems...

    Yeah, using aerosols, and being new to this, I am guessing you have a few thin spots in your clear. Be VERY careful scuffing, and make sure you don't put the next coat on too heavy or you will start to lift it (wrinkle it). If you spray too close you run the risk of the propellents damaging the previous coat as well, so make sure you keep about 12" of distance when you spray.

    All great advice.
