Thread: Wrinkling Base coat

Tweet

dody,

Heres my thoughts :

1 rubbed down my roof keying the original factory laquer then recoated in base coat then non poisionus 2-pac laquer about 6 weeks ago the roof came up very nice.

For one , manufacturers do not use lacquer anymore .

2.had to tape over my sunroof opening with a black bag 2 weeks later to remove and clean the paint from my sunroof frame, When removing the masking tape the laquer lifted with it a strip about 1inch wide by 1.5 inches long

Usually when paint peals when the tape is pulled is because of Improper sanding of the panels around tight edges .

3. read up on spot repairing on Internet and attempted to repair damaged section without rubbing down whole roof and respraying the whole lot again. ?
Are you just rubbing the surface with compound ? or using 400-600 wet to prep the roof ? This insure BITE of the new paint from pealing .
?
4.flatened down the damaged bit with various grades of paper then sprayed some base coat onto it, The edge around the repair which was feathered out began to wrinkle just the edge .
What type base and product are you using ? are the base and clear compatible ???

5. allowed it to dry then rubbed down again being very fussy this time with prep work and cleaning the area with panel wipe. tryed again same ***** happened. ?

Like HRP said , its the reducer/thinner that is attacking the feathered paint edge . Try sealing off the edge wit h a compatible sealer, or try cutting down on the material sprayed over the edge , very light coats MAY help in stopping the lifting .?

6. rubbed down again and sprayed some of my non poisinuss laquer over the repair to seal it in.

Lacquer is HIGHLY poisonous , the highest VOC content of all paints , its why it is being fazed out !??

7. 24 hours later gently rubbed the laquer flat with 1200 grade and cleaned the area, Sprayed some base coat over repair then 2-3 coats later the new laquered edge around repair began to wrinkle the old edge on original repair beneath was fine

The base coat your spraying should be compatible with itself and NO lifting should occur , unless its been clear coated with a different type product , then if you going back over the clear with the base , this is why your having lift problems . The base is attacking the clear edge .
I need to know more about the products you are using to have a better understanding of WHY your having lifting problems .
Lacquer will never lift itself , its usually what is under the repair or , an Un-Compatiable product over the top of it , and trying to spray lacquer over this , and breaking this surface , allowing the penetration of the thinners to attack the feather edge !
Hope this may shed some light on the subject .
