Sanding Primer

[Matt11]

What grit wet dry sand paper in best to sand primer before applying the finish paint coat?

[Matt11]

Thanks so if I sand with say 600 grit this sound be ok? Also when do I spray lacquer over this coat?

[Matt11]

Thanks do I need to wait for the finish coat to dry long before I apply the lacquer

[Matt11]

Thanks I'll get some 600 then. After I spray the finnish coat how long do I need to leave before I spray the lacquer?

[Matt11]

some people say 20-30 mins after base coat some same 24 hours?

Don't wait 24 hours, the laquer won't adhere to the paint properly.

Thanks so you recommend 20-30 minutes?

I put the lacquer on after about an hour and it reacted badly. Turned the colour from a good colour match to a dull dark grey. Is there anyway I can re-spray the final colour coat after wet dry sanding or would I need to sand back to the primer something I wouldn't really want to do. Thanks for any advice.

Can I wet dry sand the paint back a bit with say 1000 grit and re-spray?

you can rub the lacquer off, re-apply another layer of colour coat over the last colour coat and try lacquering again... after a longer wait.

Try to keep the rubbing even so you don't get patches of primer showing through the old colour coat though because you may be able to see subtle colour changes on the finished article.

Thanks for the re-apply, What grit wet dry would you recommend on the colour coat before I apply a new coat off this?

[Matt11]

Thanks and should rubbing down with say 1000 leave enough key for the paint to stick to hopefully?. Just wish I had waited longer now it looked pretty good before the lacquer.

[Matt11]

Thanks I have done it and it looks decent. I don't think I am going to try lacquering it after last times problems. Should the paint still be ok without lacquer?

[Matt11]

with the lacquer reacting badly last time I am not realy wanting to try again. What do you mean wear off quickly?

[Matt11]

Could I use some kind of wax instead?
