Wrinkled basecoat

    Sprayed Eastwood epoxy primer.

    Then Eastwood primer surfaced.

    Chose to skip a sealer. Went straight to basecoat .

    Sherwin Williams pro line basecoat. Mixed 1 to 1 with reducer.
    Code 17 silver mist paint.

    It wrinkled the 1st coat.



    I am looking for suggestions on how to address this. Not a show car, just a driver.

    Thanks for any remedies

    Sounds like you had extreme temperature or a chemical reaction depending on how large the area may have to strip and start over. Not a good idea to mix products. It also voids any warranties.

    Was the primer surfacer lacquer or a 2k urethane ?

    2K Urethane

    The weather did dip once I got started. It was like 45deg and rainy humid.

    Painted in my garage.

    I let everything flash longer, but maybe not enough?


    I am thinking.....maybe I have another go at it, but run the recoat times all the way out to get rid of as much chemical as possible before basecoat.

    I have a hood scoop partitioned up to test several different scenarios of how to address this. sanding, new surfacer, sealer, etc etc different combinations of operations. Maybe go real light on the base at first to "build it up"?

    I would hate to call the $350 color a waste.

    How long did the primer dry? I assume you didn't go wet on wet with it and the base ??

    primer dried a couple days. was sanded. then base applied.

    How large of an area?
    Is the wrinkle consistent or patchy?
    Can you post or send me a pic

    whole car. It didn't wrinkle immediately. but when I went to apply second coat of base, there it was.

    Interestingly, it was worst wrinkled where the basecoat was heaviest, though it had an effect everywhere. It looks like one of those crinkle paints with cracks and everything in it.

    Couple causes

    1. too much material was applied too fast
    2. Contamination caused by a incompatible precleaner,...not likely
    3. Primer was still soft due to insufficient activator

    Base is never intended to be sprayed wet,..you pick the gun up a good 10in from the surface and maintain that distance as best as you can no matter the shap of the panel

    there were a couple spots where I had gone back and primed a bare spot with reduced primer prior to base.

    Those spots fared well and didn't show wrinkling.

    What temp is or will the area be when you respray it?

    probably 65

    being a silver I would use a normal or "mid temp" reducer

    But you will need to sand the entire car with 800 to level the wrinkles, then it sounds to me like you need to move faster along the panel , open the pattern all the way and maintain your distance spraying consist of really only 3 variables "SDO" Speed , Distance and Overlap if you keep those 3 things In Check and consistent you'll be good. Dont try to make it silver with one coat plan for and expect 3 to 4 coats

    Once you get it scuffed and ready try an area as described and if it does something wonky then we have a chemical problem rite now based on what your telling me I feel like it's an application problem

    If you are using the Sherwin Williams "ultra 7000" base you must use the matching reducer,..standard urethane reducer will work with it,..now that I think about it if you do it will wrinkle iirc been a few years since I messed with any of that SW stuff

    The only SW base available is the "Dimension" the "ATX" and the Ultra 7000 the first two you can cut with any reducer

    If it makes you feel any better,...Sherwin Williams is also known as Shrink and Wrinkle in the automotive paint industry

    Thanks

    I got a half gallon of (PBTC) "Pro Base Intermix" and a gallon of (PB2204) "Pro Base reducer medium", both from the SW/Napa store. I am painting only the top of an 84 Hurst Olds

    The code 17 silver reallt spotlighted 400 grit scratches, so I am considering going with surfacer again to sand with a finer grit, like 600. then go after the base again.

    They have pretty nice Euro clear in the ATX line 5liters for around $150 for the kit,..that's my price thru school,..I bought 6 kits few months back it sprays really nice has really good gloss retention its certainly not a top 5 product but nice

    LOL yea that fits. Lesson learned.

    I had no such issues when I did my green 72 with Eastwood and PPG products.

    Only technique and gun setup issues.

    For silver you want to final sand with the 600 or even 800,..the metallic will lay better over the 800. No real need to re prime,..just smooth up what you have and then seal it then go straight to color, unless its wrinkled really bad but one coat of base will sand rite off
