So I picked up an OE GTi rear lower valance today from my local TPS.  On my way home I stopped in at a body shop I have used in the past, for a quote on painting.  After having to give my entire life history to the rude, arrogant and obnoxious receptionist she sent for the estimator.  Well to say I was shocked by the prices quoted is an understatement.  

Quote #1: Prepare the textured surface with high build plastic primer then paint - £128 +VAT (he did say that it would probably flake off though).
Quote #2: DA the surface to remove the textured finish then build the surface back up with filler/primer then paint - £240 +VAT!  

Question here is do they think I'm a mug or is that the sort of price I will have to pay?  Also is there any way I can prepare the bumper by sanding it etc?
