Paint peeling
It may be because the surface is too smooth. If the original paint is lacquer or powder (with untreated sizing paint), the new paint will not stick to the surface. Or it may be wood decay or metal rust, or peeling off due to poor paint quality.
A small area of ​​paint is peeling off. It can be sanded with fine sandpaper, then put on, putty, brushed with primer and repainted. Exfoliation over a large area must scrape all the paint off and repaint it.
Paint foaming
First of all, the puncture is broken. If there is water coming out, it means that under the lacquer layer there is moisture infiltration underneath or behind it. After the sun shines and the water evaporates into vapor, the paint is lifted up into foam. At this point, the blistering paint is removed with a hot air gun, the wood is allowed to dry naturally, then the primer is applied, and finally the entire repair surface is repainted.
If there is no water in the bubble, it may be cracked wood grain, there is a small amount of air, the sun through the sun, the air expands, the paint bulge. Faced with this situation, first scrape off the blistering paint, then use a resin filler to fill the cracks, repaint it, or use no filler. After the paint is peeled off, apply a microporous paint directly.
Cracked
In most cases, the paint must be removed with a chemical paint remover or a hot air gun and then repainted.
If the fracture range is not large, then sanding blocks or wet or dry sandpaper can be used to dilute the broken paint. After the surface has been smoothed, apply putty, apply a primer, and repaint it.

Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.
Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.circle wedge,square wedge,irregular wedge...Every materials,sizes,wedges and coatings may be available by custom orders. Standard and broadband antireflection coatings are available upon request.
