    Thanks, I am using das sealer but I may have a problem, I used the one choice plastic prep system, and the surface just didn’t look right after doing the prep, I then applyed the das sealer, it looked blotchey, or something like fisheyes without the craters, or like spots all over it. So I wet sanded the sealer and re sprayed it, Still looks like spots on a lepoard, is that normal, after preping and sealing a plastic ?

    Thanks, for the help

    If the the das sealer your talking about is PPG they recommend two coats on plastic parts or poly cut threws one coat will sometimes give that appearance

    Thanks,
    Yes it is PPG das sealer and it is the second coat, I have never seen anything look like it before, but it is my first time using the ppg prep system.

    Thanks

    DAS on raw plastic can give you fits. When it first came out, if you waited a few minutes too long before basing it would wrinkle on you

    I always thought flex agent was only temporary. Like only flexy for a few days. No info to back it up though.

    Some are like PPG’s. others that are true elastifiers are permanent like the ones used in akzo systems or basf

    PPG claims in their Auto Color line they have the only true Elastomeric, it stays in elastic flexible state. PN#2021

    So you mean Nexa has the real stuff. makes sense since it’s a good European paint line :p

    Good to know! I bought a few old 1970’s Honda ATC 70cc three wheelers and I was considering painting the plastics. Would need something that would stay flexy.

    ici/nexa do have a really good flex additive that remains flexible

    Dunno about over the pond in the late 80’s early 90’s quite a few cars were fitted with soft foam filled lip spoilers.

    These were very soft you could pinch them beteween your fingers and they would compress like a regular sponge.

    Add the flex additive and amazingly the paint would stay intact and not split or spider web.
