marky boy Posted June 6, 2007 Report Share Posted June 6, 2007 Yikes , aerosols!! The final finish will only be as good as the preperation Scotty. Have a good look at your primed and sanded finish and imagine it glossy cos that is all that will happen when you put on the topcoat. It will just highlight the primer with very little 'fill'. 1st move for cellulose cans is as you pointed out , it must be warm , if not the paint will 'bloom' ie go cloudy and look bloody awful. One trick is to put the cans that you are going to use into a bucket of hot water to warm up the cans and paint until you are ready to use them. BE PATIENT !!! Put your 1st coat on reasonably dry (a speckle coat i call it) and let it flash off(this will give the topcoat a key). No need to sand it down but then then apply another wetter coat. Leave for 15 mins ish between coats (depends on how wet you put the last coat and really until tacky) and then apply again. I reckon after your speckle coat coat 2-3 good full coats should do it. The last coat is the finishing coat so will requirea little more but dont get too carried away as you can soon ruin the whole job with a load of runs in the last coat!! Bear in mind that to awkward to paint places tend to be the same places that you will get your runs.(from brackets and lugs etc) Hope this helps Mark Quote Link to comment Share on other sites More sharing options...
andy.t Posted June 6, 2007 Report Share Posted June 6, 2007 Hi,if the spray can has a standard nozzle I would try and fit the type that comes with the larger cans that are supplied with car body panel spray cans,these will give a fan spray effect and if you spray the paint down the tubes with fan going down not across then you will get more paint on the frame and not in the air.You can apply as many coats as you like if the last looks good then the next should to,let coats touch dry in between, if any get a bit rough just flatten back with the wet and dry and apply more.Try to keep the paint looking wet as you spray and do long strokes from top to bottom of each tube section.If you spray when its too hot like 25dgc then you will find it hard to get a good finish anything as low as 10dgc on a dry day should be fine. Regards Andy. P.S. thats what I would do but could be talking out of my RSSSS. Quote Link to comment Share on other sites More sharing options...

scotty Posted June 7, 2007 Author Report Share Posted June 7, 2007 Thanks for the replys! Im doing the frame in spray cans as my local powdercoater couldn't match me the proper shade of blue! also i think it makes the bike look a lot more original as you can spot powdercoat jobs a mile away! mmmmm! I should have wet+dryed it down a bit more as has been mentioned what you start with is what you'll finish weve! if i flat it back with wet and dry should this be used with water? the w+d is 600 grade! any way thanks the advise is top notch! now back to the shed!!!
