kodiakblair Posted June 26, 2018 Share Posted June 26, 2018 (edited) Made an derrière of things last night. Did 2 light coast of poly before I spotted the can was satin not gloss. Can I just spray over with gloss or do I need to sand back again. Cheers KB Edited June 26, 2018 by kodiakblair Quote Link to comment Share on other sites More sharing options...
Maude Posted June 26, 2018 Share Posted June 26, 2018 If it's the same type of paint then it'll be fine, just very lightly key up the surface (2000 wet 'n' dry or a scotch pad) if dry and gloss over. If the coverage is acceptable you could just clear lacquer on top. I always prefer a coloured basecoat then lacquer to a colour topcoat. You get a better depth of finish. 1 Quote Link to comment Share on other sites More sharing options...
kodiakblair Posted June 26, 2018 Author Share Posted June 26, 2018 Thanks @Maude Gave it a scuff earlier. Had choice of Dulux clear (4 hr between coats) or Halfords clear (15 minutes). Went for Halfords. Instant "Crackle effect" finish 🤬 Quote Link to comment Share on other sites More sharing options...
Maude Posted June 26, 2018 Share Posted June 26, 2018 What paint was the satin? Quote Link to comment Share on other sites More sharing options...

The colour is Rust-oleum Painter's touch. The Halfords that went crackle was acrylic,says it works with all car paints so I'm stumped at the reaction. Bloody tough stuff to rub off again 😀 Quote Link to comment Share on other sites More sharing options...
Maude Posted June 26, 2018 Share Posted June 26, 2018 I think I misunderstood your original post. I assumed the satin was a colour top coat, but it was a satin clearcoat over Rustoleum colour coat, yes? It doesn't matter anyway. The only thing I can think of is differing drying times. You can get crazing if the top coat is very rapid drying and the basecoat is still soft. The top will dry and then crack as the base moves. But I don't think this is the problem if it happened pretty much instantly. Just differing types of paint most likely, acrylic is normally a mix of acrylic and urethane, poly is a mix of different urethanes but what the mixes are is anyone's guess. What I meant when I said same type of paint was the same brand and type, ie Plasti-kote clear satin poly and Plasti-kote clear gloss poly. That's the trouble with cheap aerosols, there's no standard mix across the board, also the high solvent contents don't help matters. Quote Link to comment Share on other sites More sharing options...

kodiakblair Posted July 5, 2018 Author Share Posted July 5, 2018 That's a nightmare @Jimothey Afraid I can't offer much bar my sympathy. I sanded the satin off then used a Dulux gloss, that worked fine. Well worked fine until I moved on to the next stage of the finish. Details of that debacle hopefully wont be published until long after my death 😉 1 Quote Link to comment Share on other sites More sharing options...
Grangur Posted July 9, 2018 Share Posted July 9, 2018 Satin is the same as gloss, but with chemicals to make the surface dry in a less-smooth finish. The easy answer is to get a seriously soft cloth, and T-cut and give it a polish. Whoops... sorry. You really don't want to know this now, do you?
