Yes I meant Paint reaction due to incompatible materials....doesn't matter a hoot if the paint is dull after rubbing down the lacquer will bring back the shine....BUT as I said paint a piece of scrap first with the green before you put the Halfords lacquer on top of it ......just in case
I find that odd .
1 I have used both Hycoat and Halfords on the rest of the boat no problems .
2 . The green Hycoat was sprayed on top of green Hycoat . then masked off so no Halfords white could have touched it.
The only thing that touched the green was X3 different type of tape .
A big thanks for your help and advice . I hope to try and sand it down on friday night .
