    Default Dulux hi gloss and wrinkles

    I am ready to clear coat a guitar body. [see my previous post] I have used Dulux hi gloss as a colour coat.

    I painted the dulux on a sample piece for a test and after a couple of days, rubbed it back a little with 800 wet n dry. After 24 hours I painted a coat of bondall ultra gloss on top. Horror upon horror, the dulux wrinkled.

    Hopefully someone can tell me why this happened and how to avoid it happening on the guitar body that i have spent much time and effort on.

    It is probably a simple solution and thanks to anybody with a tip or suggestion.

    I'm not conversant with the products but it sounds like 2 possible causes
    1. The Dulux needed to dry for a lot longer, I'd give it at least a week in winter.
    I'm inclined to think this is the major problem.
    2. There may be a compatibility issue between the finishes. Do they both clean up with the same stuff (turps etc).

    If the problem is caused by incompatible finishes you need to seal the dulux, probably with shellac. White shellac won't alter the color at all.

    At a guess.
    dulux turps based enamel? Yea?
    Two pack laquer, thinners base?
    Problems will occur.
    You would probably have problems with single pack turps based poly too.

    For future reference.
    Thinners based undercoats & turps stuff over, you will probaly get away with it.
    Turps under, thinners over, problem.
    enamel & poly, probably problems.

    If you must go the hardware store road.
    Wattyl estipol snading sealer (or similar), poly paving paint (black or colour), clear poly over (if you must). The paving paint will be plenty hard & cand be rubbed out to a nice gloss. All hard work & slow drying though.

    enamel is great for houses but it trecherous as a fine finish.

    cheers

    mmm Both the hi gloss enamel and polyurethane clear are turps based products. The posts rec'd i have one saying i will have problems with the poly clear and one saying dry it out well before applyiing the poly and it will be ok.

    Is there another clear product i could be looking at, or just go with the dulux and no clear coat?

    Thanks for your interest.

    you should be able to bring the dulux up to a fine finish but you need to rub back between coats.

    Picker mate I'd just give the enamel a good rubbing out & maybee some EE ultrashine.
    As a general rule you can use finishes from the same family over one another reasonably safely, But mixing families can be "interesting".
    You will probably get a reasonable result but next time there are easier ways than enamel.
    I've heard of worse things done to guitars.

    I am going to go with soundmans advice and rub out the dulux and polish it.

    Noting soundmans final comment

    "I've heard of worse things done to guitars."

    Has anybody got advice on how to do a solid colour mirror finish on wood properly without using nitro? Maybe water based?

    Any thoughts on this subject would be greatly appreciated as I am planning my next guitar project and I really like the sporty 60's type colours used on the vintage Fender slab type electric guitars.

    thanks again

    Nitro is realy the finish of choice for gituars for a variety of reasons, However.
    How about french polishing over some solid colour underfinish.
    or pouring laquer ( e-poxy) over whatever you like.
