fullscreenaging Posted November 3, 2015 Posted November 3, 2015 Looking for a bit of advise....I'm experimenting with some hydro dipping in the next few weeks so am in the middle of prepping my hand guard plates.I have stuck plastic primer on and am in the process of applying the colour. Now the bit I'm a little unsure of is this;Once I've finished with the colour do I sand it down (I have some 2000 grit) before I polish it to make it shiny) if so is it best to use it wet or dry? I will be dipping some carbon effect and then sticking a lacquer over the top when done.Anyone with experience of DIY spray painting?Thanks in advance! Quote
cockercas Posted November 3, 2015 Posted November 3, 2015 Wet. Loads of water so the paper dosnt clog.Just done my whole bike. What paint is it? Celluose takes a while to dry propley.You dont want to polish it with polish. You want a proper compound and use it with plenty of water. Quote

Celluose takes a while to dry propley.You dont want to polish it with polish. You want a proper compound and use it with plenty of water. Cheers for that. It just Halfords stuff. I think it's celluose as it states on the the tin to allow two weeks to fully dry.I'll pop to Halfords again and get some compound stuff [emoji106] Quote
Stu Posted November 3, 2015 Posted November 3, 2015 I dont think the public can easily buy celluose any more Quote
fullscreenaging Posted November 4, 2015 Author Posted November 4, 2015 Cheers Stu. Don't know much about paint. Going to get some compound later. Just to clear this up. Can I use the compound before putting the lacquer on? Quote
Stu Posted November 4, 2015 Posted November 4, 2015 no don't put anything on before the lacquer! it probably wont stick! seen as though they are small items you can do a bit of trial and error without too much worry some paints require sanding between coats some don't If I was you I would do one with sanding between every coat and then sand before the lacquer if it looks shit or its not shiny then do the other with no sandingbe careful around the edges as it can easily go through to the primer Quote
fullscreenaging Posted November 4, 2015 Author Posted November 4, 2015 Nice one. Thanks for the advice I think with the carbon effect going over the top it should hide any imperfections so I can experiment as you suggested. Quote
Stu Posted November 4, 2015 Posted November 4, 2015 why didnt you just get some carbon vinyl wrap for them Quote
fullscreenaging Posted November 4, 2015 Author Posted November 4, 2015 I tried that but too many pointy edges. It looked good on the flat parts but getting it round the pointy bits and to the inside got really messy. Quote
Stu Posted November 4, 2015 Posted November 4, 2015 ah fair do's then yeah I forgot yours a bit pointy Quote
cockercas Posted November 5, 2015 Posted November 5, 2015 I dont think the public can easily buy celluose any moreYou can, theres a industral estate just past mt pleseant. Got all my stuff from there.Or loads on the bay. Quote
cockercas Posted November 5, 2015 Posted November 5, 2015 Halfords rattle cans deffinetly need sanding.Do you need to polish it with hydrodipping?Prime it with 3 coats.Sand it smooth with 2000/3000 grit wet and dry.2 coats of colour then sand.Then 1 coat of colour.If you laqure over celluose to soon then it stays soft.If you laqure over the hydrodip film do 3 coats, leave a couple of days then do 2 more coats.Then to get it really shiney get some ultrafine/fine compound on it.A polishing kit for a drill helps.Wet the sponge though.

fullscreenaging Posted November 5, 2015 Author Posted November 5, 2015 Cheers Joe.Right, I've got the colour on. I did two coats on Tuesday then flatted it. Then did 2 last night. I think I'm going to have to flat it and polish it before hydro dipping as I have a bit of orange peel and I'm not sure that the film will stick to the orange peel.Any more advise on this guys? Quote
cockercas Posted November 5, 2015 Posted November 5, 2015 Orange peel is caused because when the paint is sprayed it comes out in tiny drops and then explodes on the plastic. It would stick. Ask someone who hydrodips if the orange peel will effect the way it lays on it though. Quote
Stu Posted November 5, 2015 Posted November 5, 2015 Actually orange peel is caused by the paint drying too quickly Or not enough paint in the first place which results in it drying too quick Quote
fullscreenaging Posted November 5, 2015 Author Posted November 5, 2015 I've had a chance tonight to have a good look at them and I don't think it's orange peel, but they feel a little rough even though they look shiny ish. I reckon the dip will go on ok. I'll take photos once they are all sorted in couple of weeks Cheers for the advise guys Quote
cockercas Posted November 5, 2015 Posted November 5, 2015 Celluose is touch dry in seconds.I googled the shit out of it before i started painting and thats what came up. Quote
cockercas Posted November 5, 2015 Posted November 5, 2015 Did you sand it back with 2000grit after the primer? Should be like glass then put the colour on. Quote
fullscreenaging Posted November 6, 2015 Author Posted November 6, 2015 Did you sand it back with 2000grit after the primer? Should be like glass then put the colour on. This could have been where I went wrong. I did sand it back, but it wasn't like glass. I misinterpreted and thought it had to be a bit rough in order to get a good key and that after a few coats it would even out. If it goes tits up I can always start again. [emoji16] Quote
cockercas Posted November 6, 2015 Posted November 6, 2015 The primer should be really smooth before you put the colour on. Quote
