silicone or slightly hard laquer??

[BigbaRd]

I had 3 maybe 4 coats on it that were more or less perfect but I couldn't leave it alone just had to add one more coat. I think its the hardener in the laquer in the gun going a lil bit hard? (been in the gun a while waiting for each coat to dry) causing that bobbly rough effect in the laquer. It wasn't their till I put the last coat on (I don't think?) and it's only on the bottom right and theirs abit up the top:

bottom right where the masked up volume and tone knobs are:





crappy camera - it's shinier than it looks and stained green/black sunburst effect (doesn't show in the pic)

is it silicone in the air or the laquer starting to go hard before i'm finished with it?

better picture of it actually:

[BigbaRd]

no-one who has sprayed laquer has had this happen?

[Tathan]

that's a guitar.

isn't that what happens when you put too much lacquer on when its not dry yet?

anyhoo, what did you use - need to repaint my SG after major structural repairs lmao

I was thinking that too, I'd have thought mike or alistair would know for sure as it's the same wether it's on a guitar or a car.

You could try cutting it back with 1200 grit and lots of soap. but i reckon you'll need to go right down and repaint it unfortunatley

Did I hear my name mentioned?

Sorry, Sometimes doing my job gets in the way of hanging about here...

Looks to me like too heavy a coat of lacquer, either too slow with the gun, to much material flow, or not allowing it to dry between recoating. This is celly or 1K? leave it plenty of time to set up between coats in this cold damp weather.

As suggested, use soapy water and fine grit to flat it off so you have it smooth and matt, then buff up with compound. If you break through you'll need to key and recoat.

Just spotted you mentioned hardner. So I guess its 2K.

Could be dry spray but looks deeper than that to me from the photo although it could be a deceptive picture.

Either way a GENTLE cut and then polish should sort it.

Pot life in the gun depends on how much hardner you used, check your data sheet for info on that.

cool, cheers best way to describe it is like the surface of an orange in them areas i've marked up. I noticed as I was putting that last coat on soon as it touched the surface that effect started showing. It was icy out too, yeh 2pacl laquer it is. Some careful but hard wet sanding with plenty of soap (need to wait about a week for it to dry propperly first or chunks might come out) then polish all the scratches out with some compound (tcut / Autoglym) and then a polish to seal it

Quick cut & paste...

Orange Peel

Inconsistency, Levelling, Orange Peel, Pebbling, Poor Flow, Uneven Application

Pebbled, uneven surface of the paint film, similar in appearance to orange skin.


Cause

Failure of the paint droplets to coalesce on the surface.

This may be due to:

a) Poor spraying technique, spray gun too far from surface, incorrect compressed air pressure, incorrect nozzle adjustment.

b) Excessively thick or thin film.

c) Paint incorrectly mixed, wrong viscosity, poor quality or incorrect thinner.

d) Insufficient drying time between coats, cold air fanning to speed drying.

e) Incorrect ambient or surface temperature, draughts.

Prevention

a) Use the correct spraying technique and ensure that equipment is correctly adjusted.

b) Apply paint in thin even coats.

c) Ensure that the paint is correctly mixed, use only recommended thinner with the correct grade.

d) Allow sufficient drying time between coats.

e) Spray within the recommended temperature range and ensure proper ventilation.

Rectification

Rub out the orange peel, compound and polish. In severe cases it may be necessary to flat and repaint the surface.

Difficult to pinpoint from the pictures - it doesn't look quite like it's gone on too dry. However, after 4 coats either the viscosity of the paint would have been too high or you weren't leaving long enough between coats as 2-pack usually needs 5-10 mins between coats at 20-25 degrees with good air flow. Ideal working time is likely to be 30-45 mins before the viscosity has risen too high for good application.

Alistair has already told you how to fix it. If you do rub through and have to start again, mix up enough for 2 coats and then when they are done mix up some fresh for the final 2 coats to ensure good application. And try to find somewhere a bit warmer if you can!!! If not get fast thinner and hardener.

gonna give it a go see if I can get it smooth without cutting it too far back, be a shame to have to re-stain, I really like the effect i've got out of it (it was an ugly orangey/yellow before)





best to wait bout a week for it to dry i've been told, chunks coming out of it whilst wet sanding is the last thing I want.

won't ask what happened to the other spikey Duo ball

I like your cushions lmao
