There must be some contamination on the bumper to make it bubble like that.... I would flat back as well as you can, get rid of all the bubbling, clean it well with water, dry it off and try again. |

Posts: 1,550 Thanks: 4 Trader Rating: 0 ![]() | Re: spraying help for god sake do not use paint stripper on bumpers because if its plastic it will melt it and if its a glassfibre bumper it will disolve the resin just use 240 grit wet and dry paper loads of water and soap then 400 grit, then 800grit its worth all the time and effort and why did you getbubbling ive only heard of that happening when putting the laquer on too soon which creates solvent poping

Posts: 3 Thanks: 0 Trader Rating: 0 | Re: spraying help For the job to last you need to use the right paint, if it is glassfibre/kevlar/carbon fibre air dry is ok but use an etch primer before grey primer. If it is plastic you have to use a surface modifier (sold as clear plastic primer by upol) and 2k paint with plasticiser will be a whole lot more durable than air dry(cellulose) We usually charge £100 plus tax to paint a new bumper.

Posts: 7,688 Thanks: 35 Blog Entries: 16 Trader Rating: 2 ![]() | Re: spraying help I used halfrauds spray cans for the primer and colour and then some 2 pack lacquer . ive used this combo before and didnt have a problem. did my back bumper with it and its got a gorgeous finish (although its not perfect). i really dont know why it bubbled but nevermind. ive redone the lot using just halfrauds spray cans and the halfrauds lacquer just to make it easier. its currently drying now and looking good.. will see proper in the morning

| Re: spraying help Paint / lacre sometimes bubbles if the surface is contaminated with silicone.. You didnt rub it with a cloth before hand that may have some silicone on it (from back to black for example). I had major trouble when i resprayed my uno last summer cos of that stupid back to black ![]()

Posts: 1,550 Thanks: 4 Trader Rating: 0 ![]() | Re: spraying help The worst things to cause silicone spotting is as you say back to black but also if you have polished something in that area in the last hour and buff it off the tiny bit of dry polish can land on the sprayed item and cause silcone spotting as alot of polishes contain alot of silcone which is why people never polish in spraybooths. Also bushboy if youve used spray can laquer then it will be single pack rather than 2 pack so the shine will be no where near as good and aint as durable and why havent you got a compressor and spraygun yet you cheap sod ![]() wayne
