dan4 Posted September 6, 2007 Share Posted September 6, 2007 i bought 2nd hand whiffbitz nosecone some while ago from Terry S. When i picked the bumper up it was primed but obviously still required. Finally got round to getting it prepped and sprayed and have now found hundreds of "blow holes" in it Has anyone had this as i am starting to wonder if the bumper was damaged and repaired poorly as the "blow holes" would indicate air in the glue used when creating a fibre glass mould poorly???:search: Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 6, 2007 Share Posted September 6, 2007 More likely "fish eyes" due to silicone contamination of the primer, have you got a pic? Quote Link to comment Share on other sites More sharing options...
dan4 Posted September 6, 2007 Author Share Posted September 6, 2007 no this is much more severe than fish eyes, the bumper is too far away to get pic before its re prepped if it isnt already. If you imagine it looking like you firing tiny air rifle pellets at it, they are actual holes in paint rather than deep blemishes Quote Link to comment Share on other sites More sharing options...
Guigsy Posted September 6, 2007 Share Posted September 6, 2007 i had one of these i baught 2nd hand off someone on ebay. it looked fine but when knightracer prepped it the fibreglass was very very thin (you could see through it) ended up being about the same ammount of money to buy a new do-luck and put that on instead as it was going to take them a whole day to prep it properly... Does it look anything like this? Quote Link to comment Share on other sites More sharing options...

paul mac Posted September 9, 2007 Share Posted September 9, 2007 when the body shop that re-sprayed my car prepped the fibre glass bumper they baked it for a couple of hours before spraying, the guy told me they do this to release any trapped gas in the fibre glass as the first time the car is exposed to sunlight/heat it will form bubbles and knacker the paint work, it sounds like yours was not baked Quote Link to comment Share on other sites More sharing options...
louisjames Posted September 12, 2007 Share Posted September 12, 2007 you get holes when its being primed/preped if you dont blow it all out with aiirlines, same with building filler, each coat you have to blow out or else it pits shortly after being painted.

Guest Chumpalot Posted September 12, 2007 Share Posted September 12, 2007 I have a similar sort of effect on my rear bumper. It's getting worse too. Quote Link to comment Share on other sites More sharing options...
