TurboTobz Posted October 28, 2012 Share Posted October 28, 2012 (edited) Just brought a 98 spec front bumper for a good price but it has a round cut hole for a side exit and a bit below the fog cut for a larger intercooler pipe section.Can anyone tell me the best process for trying to hide these away? will upload pics soon for extra detail.Thanks Edited October 29, 2012 by TurboTobz Quote Link to post Share on other sites

shorty Posted October 28, 2012 Share Posted October 28, 2012 Fibreglass and resin based filler. Quote Link to post Share on other sites
AdamB Posted October 28, 2012 Share Posted October 28, 2012 ^^^ x2, best to place a piece of wood or thin metal sheet behind the side your going ti fill. As sometimes it will sink as it dries. Quote Link to post Share on other sites
aaddzz123 Posted October 28, 2012 Share Posted October 28, 2012 You're going to need to fiberglass these matey. It's quite easy stuff to work with and you can get kits on ebay. Work on the inside of the bumper and make sure you really rough up the surface you're sticking the fiberglass on to try and help prevent cracking or splitting from the bumper etc. Use plenty of it too and go a fair bit wider than the hole. You don't really want that bit flexing because once you've got the hole covered from the inside, you're going to have the fill the recess thats left using body filler. Epson's P38 is widely available... Use a sanding block would be my best tip. Don't want wavy ripple repairs lol. Quote Link to post Share on other sites
Ryan-11 Posted October 28, 2012 Share Posted October 28, 2012 i would plastic weld it but if your doing it your self then fibreglass is easier, make sure u get filler that will stick to plastic as some fillers dont, i would fibreglass the back, then use this to fill the recess http://www.ebay.co.uk/itm/U-pol-SMC-White-High-Adhesion-Easy-Sand-Plastic-Filler-/110683106220?pt=UK_Body_Shop_Supplies_Paint&hash=item19c53a2bac then a final skin of this filler http://www.ebay.co.uk/itm/Evercoat-Easy-Sand-Stopper-/160634578923?pt=UK_Body_Shop_Supplies_Paint&hash=item25669127eb Quote Link to post Share on other sites
A L 3 X Posted October 28, 2012 Share Posted October 28, 2012 I would also plastic weld then skim with filler, fibreglass will crack Quote Link to post Share on other sites
aaddzz123 Posted November 3, 2012 Share Posted November 3, 2012 Fiberglass won't crack if done properly. It'll be more rigid than plaggy welding which is kinda what you want considering you're putting filler over the top of it... The more flex and movement behind the filler, the more likely the filler is to crack....Each to their own. Do what you feel is easy. Either way, if you have a bump, the filler is going to crack or dislodge because you're filling a flexible object and filler doesn't flex . Which is why I personally would use fiberglass to reduce the flex. Quote Link to post Share on other sites
A L 3 X Posted November 3, 2012 Share Posted November 3, 2012 If he took a lot of time and effort plastic welding would be possible without much if any fillerI think fibreglass would crack as I've seen first hand, something rigid bonded to something flexible doesn't last Quote Link to post Share on other sites
Simon Posted November 3, 2012 Share Posted November 3, 2012 A 98 spec splitter would cover a lot of that up Quote Link to post Share on other sites
TurboTobz Posted November 3, 2012 Author Share Posted November 3, 2012 (edited) A 98 spec splitter would cover a lot of that up I know! That is my initial plan although money at the moment is tight hoping to be in a new job soon, awaiting test results which determine if I'll have an interview! At the moment I am out of work so I am surviving off of saved money and hoping that my ibiza cupra sells asaaaaaap! Edited November 3, 2012 by TurboTobz Quote Link to post Share on other sites
Ryan-11 Posted November 4, 2012 Share Posted November 4, 2012 Filler has more flex in it than fibreglass i would say, if u have a bump the filler will crack but the chances are the fibreglass will too, If u plastic weld it you shouldnt need filler if its done properly Quote Link to post Share on other sites
TurboTobz Posted November 4, 2012 Author Share Posted November 4, 2012 I have heared of plastic weld but I am not familiar with this, although I have some filler and a tub of fibreglass here now my friends father has offered to prep the entire bumper ready for spraying for just £30 and he is an impeccable panel beater/sprayer so I am considering this dependent on cash flow Quote Link to post Share on other sites
