Caddy r32 gti bumpers
Posted: Mon Mar 25, 2019 2:50 pm
Done a few mk7 bumpers and happy to help anyone wanting to have a go. It’s a lot of work to be honest and by the time you’ve bought the gti bumper, grills and all the time/skills to make it perfect its not expensive to buy one already made to be honest. I haven’t personally seen any others other than the ones i’ve made but the time taken to get a perfect finish is a lot of man hours.
However, these are a few pics of some ive made showing cuts and datum. I make a dry screw on fit first with bumper on the van. Find centre of both bumpers and use a guide like i show below of 157mm. Thats worked well always for me and gives adequate over lap for bonding and plenty of inner bumper room to fix the lower centre honeycomb grill etc
Then once you have your 157mm and centre screw in place, the sides of the gti bumper will fit snug to the end of the caddy bumper if cut like this, leaving the lower part of the new gti bumper that little lug in the pic to match up and line up flush with the end of the caddy bumper and screw both sides. Thats your basic 3 stage dimension all done ON THE VAN.
Then whilst still fixed to the van, screw some more screws in making a flush fit. Then remove bumper and bond with good quality PU adhesive making sure you screw into the original holes you made whilst the dry fit was being made. I use 1 complete tube per bumper. I personally prefer this method rather than plastic weld as it is more forgiving and flexible. I then leave the adhesive to cure and set for at least a minimum 24 hours. Then is a matter of removing all screws and feathering the edges to take a thin layer of (Update) UPOL SMC carbon black filler with fibres and sand down. (Update)SMC can also be used on the number plate recess and build it up to accommodate the final filler (Update - I like UPOL dolphin). I then use a good quality high build primer and then leave that settle for as long as you can and then look for any sinkages or furring you need to address before your base and laquer.
Hope this helps but the final filler work and shaping takes some patience, feel, and a good eye! Here are some pics that may help ...
