Primer

[Harry m]

do I need to prime the every thing or can I flat off the original panel and paint over it providing it's in good condition, l'm using celly and not changing the colour of the Landy.

you can just key the good old paint

No you only need to prime bare metal and as long as original paint is sound just flat it

 

[Spark plug]

No no need to prime everything you can just spot prime any bare metal areas.

Be careful with cellulose on existing paint, it may cause it to lift. Test a small inconspicuous area first.

Absolutely. If the OE paint is COB it will definitely pickle up under celly if you break through the clear coat. Its the solvent content that does it and is relevant to celly primer as well as top coat. Being a landy, its less likely to be COB so as the guys above say, just key it up for a colour change (grey scotchbrite) but if there are any feather edges from repairs, spot prime.

Excellent thanks lads will need to get some grey scotchbrite, it's a old Landy 1990 I've had it the last 19 years so should be ok
