Prepping for coating

[Britsdaddy]

I'm thinking about coating my truck with CQUK. I did a full decontamination this spring with Iron X and claying and the truck is currently swirl free. It does have 3 coats of 845 on it, though. Would another full decontamination and spraying OPC to remove the wax be enough or do I need to polish first when the truck doesn't need it?

Personaly I don't think a Decon spray and OPC is enough to remove most waxes much less 3-layers of 845. IMO your best bet is to Decon and use a finishing polish quickly to make sure you are down to bare paint. Then do you Eraser step and go from there.

Although I would not recommend polishing if not needed, but with 3 coats of Collinite, you may need a light polish to remove it. You can try washing a section of your hood with OPC mixed with Car Pro Reset and see how it beads. If it removes the 845, I would still do an Eraser wipe down before CQUK. Good luck with your new coating.

Wash it with iron-x snow foam then do an eraser wipe down and you should be good to go.

Polishing is the way to go

With three coats of a durable LSP you will need to polish the surface with a finishing polish and polishing pad to ensure the LSP is removed.

Dont take a chance. Light polish to make sure car needs to be surgically clean, you dont want to wast your time or money. Coatings need to have a good surface to bond to so they will last as long as possible. It should not take you long to polish if you have no paint correction needed.

This is a good thread. One that should be a sticky.

Thanks for everyone's input. I'm thinking to try a test spot, maybe on one side of a fenders, to see what water beading looks like with a full decon and OPC, and on the other side a light polish. I'm trying to save polishing what doesn't need to be polished.
