Some people say that a boosted h3 should be glued with elastic wbg glue like Finezip, Haifu or dhs #15. Would it be okay to glue it with Donic first formula or vario clean?
If you put the booster directly to the sponge it's okay, but if you boost through the glue layers then Finezip or Revo No.3 are the best choices. I don't know about the dhs and haifu ones.
