Reasons why car varnish loses gloss

The car body that had just been sprayed with varnish clearly had a high gloss, but why did it lose its luster the next day? The reasons why varnish loses its luster may be:

1. If the paint layer is too thick and has not dried, spray a varnish layer.
2. Improper selection of diluent
3. The ratio of curing agent or thinner is wrong
4. Polish before the coating is completely dry.
5. The construction environment and unskilled painting and spraying techniques may also cause gloss loss.

It is recommended to select the appropriate thinner according to the temperature of the construction environment, mix the varnish, curing agent and thinner in the correct proportion, and spray it thinly first.
Then leave a certain interval between every two layers for it to evaporate, and then spray the second or third layer. Do not apply a thick layer at once to save time.
