Years ago, I used to use DP40 for a sealer by thinning it with DT reducer. Last night I tried this with the new DPLF and it was dying back or bleeding through where the filler was. I let it flash in between coats and sprayed another wet coat. This morning I came out and looked at it and I can see the filler again. I use Rage Gold filler, BTW. Can you still use DPLF as a sealer? The tech sheets say you can but I am afraid to put color on it tonight.
Perhaps a coat that was not thinned over the filler, then the reduced version? Seems to me I had this happen also, but it's been a while.
i used to use the dp also and it worked great. when they changed the formula to lead free it did not work as well so i stopped using it. i use transtar sealer now. works like it should. sealed filler spot always look different than bare steel areas, or at least to me.
Are you reducing the DP according to directions? They call for very little reduction. I think you are asking too much of a sealer. I always prime over filler never expecting or relying on sealer to hide filler.
I just used the newer DAS302X PPG Sealer and it works great . Comes in three colors and sprayed out real nice . The X is for the colors 1 white-5 gray -7 dark gray . Costly but is great.
Yes, per tech sheet. I'm not trying to hide it, it's smooth and basically nonexistant to the touch. DP is considered a primer/sealer. I guess if spray color and it bleeds, I'll just color sand the color and respray. Broad as it is long. The color would end up acting like a sealer. It's a single stage urethane topcoat.
If it bleeds through color more color won't stop it. The fix is primer or sealer to hiding over the filler. Primer would be better because it won't be absorbed by the filler as much as sealer would.
